Wifes sunroof is open and will not close. Checked fuse it has pwr, removed switch it does not have power ... a ground problem at the sunroof motor...where is that?


First off this is controlled by a module (computer) The switch would only have five volts . 5volt reference voltage from the control module . Not knowing how to test the electrical circuit's for this could be expensive . Short out the module or 5 volt ref. voltage circuit inside the module.
Your best bet , take it to a qualified repair shop . Look at a wiring diagram here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on body & accessories ,then under subsystem click sun roof . Then click search button then the blue link . Now tell me you under stand what's happening here .

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof Opening Position Switch (SOPS)
• Sunroof switch
• Sunroof motor/actuator
• Sunroof glass (spoiler type, with glass sliding above roof)
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power supply for the sunroof control module: SUNROOF 20 A fuse
• Ground from G302

Sunroof Opening Position Switch (SOPS)
The SOPS tracks the position of the glass through 2 limit switches:
• Soft stop limit
• Vent limit
The sunroof control module monitors the limit switches and based on the inputs determines the position of the sunroof glass. As a limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling down the 5 volt reference to 0 volts.
The sunroof control module understands the position of the sunroof glass based on the different input combinations through the sunroof limit switch soft stop signal and sunroof limit switch open vent signal circuits.

Power Sunroof Does Not Close
Perform the Initialization/Teach Process any time a new sunroof motor actuator is installed in the vehicle or any time an existing sunroof motor actuator is removed from the vehicle. Refer to Sunroof Motor/Actuator Initialization/Teach Process .

Mazda3 Sunroof Adjustments & Repairs


Folks -

The "gearbox" is unfortunately under the headliner with no easy access. If you are also experiencing a clicking sound when the motor is activated, the regulator track had slipped position and will need to be reset.

IMAGE WONT POST, SORRY

I have been through this problem twice now. The first time the motor / gearbox came loose from it's mounts, began slipping (click, click,click), very nasty sound. I remounted the motor with threadlock on the NEW ALLEN HEAD screws, but alas.. two years later (mine's 2006) it slipped again.. I need to drop the headliner once more and have a look. If you would like a copy of your 05/06 FSM, drop me a line.


Here's the RESET procedure from the FSM, absolutely gospel, no other way to fix it:

Sunroof Motor Assembly Note:

Note
• If the guide is removed, initial position setting of the sunroof motor will be required. After installing the sunroof unit, perform initial position setting using the following procedure.

1. Press the TILT UP switch to fully tilt up the glass panel.

2. When the glass panel reaches the fully tilt up position, temporarily release the TILT UP switch and press it again for approx. 13 s continuously. Continue pressing the switch until the glass panel automatically stops at the fully tilt up position after reaching the mechanical lock position.

3. When the glass panel stops at the fully tilt up position, temporarily release the TILT UP switch, then press it again within 5 s and hold.
Note

• Press the TILT UP switch continuously until the glass panel opens to the fully open position, returns to the fully closed position and then stops.

4. Release the TILT UP switch when the glass panel stops at the fully closed position.


ALSO, Here's the clearance adjustment specs for having the glass panel in the correct resting position:

GLASS PANEL ADJUSTMENT

1. Fully close the glass panel.

2. Measure the gap and height difference between the glass panel and the body.

3. Loosen the glass panel installation screws and move the glass panel to adjust.

http://img696.imageshack.us/img696/3097/roofadj01.jpg
IMAGE WONT POST, SORRY

Standard clearance a: 0.2-2.2 mm {0.008-0.08 in} b: 0 mm {0 in}
4. Tighten the screws.

5. Insert any available thin plastic card between the weatherstrip and the body, and verify that they are sealed. (There is resistance when the plastic card is moved.)

http://img696.imageshack.us/img696/610/roofadj02.jpg
IMAGE WONT POST, SORRY

• If they are not sealed, perform Steps 3-4 and adjust again.

MAP LIGHT REMOVAL/INSTALLATION

1. Disconnect the negative battery cable.

2. Insert a tape-wrapped flathead screwdriver into the gap between the headliner and the map light.

3. Press the tab and remove the map light.

http://img94.imageshack.us/img94/2121/roofadj05.jpg

4. Disconnect the map light connector.

http://img696.imageshack.us/img696/3024/roofadj06.jpg
IMAGE WONT POST, SORRY

5. Remove the socket, then remove the map light bulb.

6. Install in the reverse order of removal.

SUNROOF UNIT DISASSEMBLY/ASSEMBLY

1. Disassemble in the order indicated in the table.

2. Assemble in the reverse order of disassembly.

Sunroof does not open. Fuse is ok and the shade operates normally.


Do you know how to do automotive electrical testing ?????? How to read a wiring diagrams ???? http://www.bbbind.com/free_tsb.html .Videos on youtube Ohms Law Tech Tip from L1 with Dave Hobbs Copy of Voltage Drop Essentials TST Motor Age The only way to find the problem , testing !

Sunroof Description and Operation (One Connector System)
Sunroof
This diagnostic procedure is to be used for the 1 connector Sunroof System that combines the sunroof control module with the sunroof motor/actuator.
The Sunroof System consists of the following components:
• BATT MAIN 2 Fuse 50 A
• Body control module (BCM)
• RAP relay
• S/Roof Fuse 20 A
• Sunroof module (includes sunroof motor/actuator)
• Sunroof switch
The Sunroof System is controlled by the sunroof switch and the sunroof motor/actuator assembly.
When the ignition is turned to RUN or ACCESSORY, or when the retained accessory power (RAP) system is active, the body control module (BCM) applies a ground to the RAP relay in the instrument panel (I/P) fuse block. This activates the RAP relay and allows battery positive voltage to be applied through the SUNROOF Fuse to the sunroof module. Ground for the sunroof module is supplied from G302.
The sunroof can be placed in 3 preset positions:
• Open
• Vent
• Closed
When the sunroof switch is placed in the OPEN position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof motor/actuator then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the full open position.
When the sunroof switch is placed in the VENT position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch open signal circuit. The sunroof module then applies voltage to the sunroof motor open control circuit and applies a ground to the sunroof motor close circuit. The sunroof motor then opens the sunroof to the VENT position.
When the sunroof switch is placed and held in the CLOSED position, a ground is applied from the sunroof switch low reference circuit , through the sunroof switch and to the sunroof switch close signal circuit. The sunroof module then applies voltage to the sunroof motor close control circuit and applies a ground to the sunroof motor open circuit. The sunroof motor then closes the sunroof.
The sunroof can be placed in any preferred open position when:
• The sunroof is in the fully opened position by pressing and holding the sunroof switch in the CLOSE position until the panel has reached the desired position then release the CLOSE switch in order to stop the sunroof
• The sunroof is opening, it can be stopped by momentarily pressing either side of the switch.
The sunroof control module, sun roof actuator, and the sunroof motor are integral parts of the sunroof module assembly and are not service separately.

Your best bet , take it to a qualified repair shop or buick dealer .

2001 cadillac deville sunroof open and want close


Check the RAP fuse in the rear fuse box , this fuse powers the sunroof control module ! Fuse Block - Rear , Left rear of the passenger compartment, under the rear seat .
The sunroof module contains the logic for the opening and the closing of the sunroof. The sunroof motor assembly contains the reversible DC drive motor, the gear train, and the limit switch.
The sunroof module determines the sunroof motor direction based on inputs received from the overhead console sunroof switches. When the ignition switch is in the ON position or when retained accessory power (RAP) is active, voltage is applied to the sunroof module via the RAP relay. For a description and operation of the RAP system, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power. The sunroof module controls the sunroof motor direction by changing the polarity of the applied voltage. The sunroof module remembers the sunroof position whenever the ignition switch is turned to the OFF position. The limit switch is used as an input to the sunroof module to indicate that the glass is fully closed, or in the comfort stop positions. The limit switch is grounded when the sunroof glass is in the fully closed or comfort stop positions, otherwise it is open.
The SLIDE CLOSE mode is initiated by moving and holding the sunroof slide switch (ROOF) forward. This applies a ground provided from the sunroof limit switch low reference circuit to the sunroof switch close vent signal input of the sunroof module. The sunroof module controls voltage to the control circuits of the sunroof motor. The sunroof motor will run until the limit switch contacts are closed. The closing of the limit switch will apply the sunroof limit switch low reference circuit to the sunroof limit switch soft stop signal circuit to the sunroof module, indicating the flush closed position has been reached. As the sunroof is approaching the close position the sunroof glass will force the wind deflector downward.
You need to have a factory scan tool hooked up an have it checked for DTC'S in the sunroof control module ! a code reader will not do this , a code reader will only check the engine codes for OBD 2 .
Important: The following must be completed before using the symptom tables.
  1. Perform Diagnostic System Check - Power Sunroof in order to verify that all of the following are true:
  2. ?€¢
    No DTCs are set.


    ?€¢
    The control modules can communicate via the serial data link.

  3. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation
your better off taking to the dealer !

Sunroof is stuck open and tried to reset it by holding button down for ten seconds and then it moves about half an inch and stays fully open. What do I need to do to get it to close?


Hi Thomas , First you should have it diagnosed by someone who has the tool to do so ! upscale scan tool , factory scan tool !
Diagnostic Starting Point - Roof
Begin the diagnosis with the Diagnostic System Check - Power Sunroof . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored DTCs and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
Symptoms
When no DTCs ( diagnostic trouble codes ) are present, begin symptom diagnosis by reviewing the
Sunroof Description and Operation . Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Roof in order to identify the correct procedure for diagnosing the system and where the procedure is located.
Important: If the suspected cause of an inoperative sunroof is a power interruption to the sunroof module, the sunroof must be re-initialized. Refer to Sunroof Motor/Actuator Synchronization .
Important: The following must be completed before using the symptom tables.

  1. Perform Diagnostic Starting Point - Roof in order to verify that all of the following are true:
  2. ?€¢
    There are no DTCs set.


    ?€¢
    The control module(s) can communicate via the serial data link.

  3. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation .
Visual/Physical Inspection
?€¢
Inspect for aftermarket devices which could affect the operation of the Power Sunroof system. Refer to
Checking Aftermarket Accessories in Wiring Systems.


?€¢
Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.

Intermittent
Faulty electrical connections or wiring may be the cause of intermittent conditions. Refer to
Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
Symptom List
Refer to a symptom diagnostic procedure from the following list in order to diagnose the symptom:
?€¢
Power Sunroof Inoperative


?€¢
Power Sunroof Does Not Open to Express Position


?€¢
Retained Accessory Power (RAP) On After Timeout in Retained Accessory Power, if the power sunroof should operate longer than 20 minutes after the ignition has been turned OFF


This information is right out of GMC service repair manual !
Sunroof Motor/Actuator Synchronization
Synchronization will be necessary anytime the sunroof module battery positive voltage circuit is interrupted. The sunroof module will be synchronized when the controller learns the full vent position. The sunroof system will ignore any open request until the system has been synchronized.
To synchronize the sunroof:

  1. Turn ON the ignition, with the engine OFF.
  2. Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position.
  3. Verify that the system operates normally.
Once the sunroof glass reaches the full vent position, the actual position is stored in the memory of the sunroof module. The sunroof module will stop the motor one motor revolution before the defined actual positions.

Sunroof on 2003 dodge neon not operating - how do you test the switch? Shouldn't I be able to test the switch itself by use of ohm meter for open/close between pins? I receive no tone between any combo of...


We would suggest isolating the wires that go to the sunroof motor and applying 12 volts and ground to verify that the motor is working properly. If it works in one direction, switch the wires to verify that it works in the other direction, fully closing and opening the sunroof. If the motor checks out okay, then the relay is your problem.

Do you know how to test automotive electrical circuit's with a DVOM - digital volt ohm meter ? When adjusting the moon roof did you see any switches ? sunroof limit switch
Measure the reference voltage of the sunroof limit switch soft stop signal circuit at the sunroof control harness connector to a good ground.
Does the reference voltage measure near the specified value?
4.5-5.5 V
Notice: Do not open the sunroof glass past the full open soft stop position. Doing so may damage the sunroof assembly and or the roof top.
Connect a jumper wire to the sunroof limit switch soft stop signal circuit at the sunroof control module harness to a good ground.
Turn ON the ignition, with the engine OFF.
Using the sunroof switch, operate the sunroof system, not to exceed the full open soft stop position.
Does the system operate as requested?

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof motor with the limit switches
• Sunroof switch
• Sunroof glass-spoiler type, with glass sliding above roof
• Sunshade
• Rail and track assembly upon which the sunroof glass rides
• Power sunroof system circuit breaker: PWR WDO 25 A
• Ground: G204

Sunroof Limit Switches
The sunroof limit switches track the position of the sunroof glass through two limit switches:
• Soft Stop limit switch through the sunroof limit switch soft stop signal circuit
• Vent Stop limit switch through the sunroof limit switch range signal circuit
The sunroof control module monitors the limit switches and based on the input combinations, determines the position of the sunroof glass. As a sunroof limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module monitors both sunroof switch input requests and based on the sunroof limit switch input combinations, will control an output to the sunroof motor, to drive the sunroof glass to the requested position.

Sunroof Motor
The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the closed to vent or vent to open position, the following occurs:
• Voltage is supplied to the sunroof motor open circuit.
• Ground is maintained to the sunroof motor close circuit.
When the motor drives the sunroof in the direction from the open to vent or vent to closed position, the following occurs:
• Voltage is supplied to the sunroof motor close circuit.
• Ground is maintained to the sunroof motor open circuit.
The sunroof control module is equipped with a timer circuit which stops the operation of the sunroof motor after 8 seconds.
