2003 tiburon power sunroof won't close all the way . It'll open all the way but starts to close & then stops.

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 .

Cheak out the channels line there glass runing one moter woking proper and othe is not working so please see the motorized scheduled root with diagram

Some sunroofs have a open switch like the drivers window. You push it and the window will open automaticly. The button on your sunroof could be jammed so even though you can close it as soon as you release it, it will auto open on it's own.

Body control module

Man mine did the same thing find out anything?

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?

Click the search button then the blue link . See the control module , motor an the two switches ? One is probably miss adjusted . or bad !

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.

check you fuses if ok then
motor or switch needs to be replaced
i think that car has a manual crank slot for manual open and close

check to see if there is damage to the sunroof guides. look at each side towards the front and see if there is an L shaped metal piece and make sure it is still L shaped.

POSSIBLE SOLUTION!! There's a seperate Tilt button and a seperate Open/Close button. Hold the Tilt buton up and the Open/Close button up at the same time WHILE THE CAR IS ON. And then turn your car off while still holding the buttons. Then turn your car back on and it should work like brand new again. This re-programs the sunroof.

If this workds for you please email at [email protected] to let me know thanks and GOOD LUCK!!!!

Check the owner's manual. There should be a section showing how to manually close the sunroof. You will use an allen wrench to turn the gears manually, I just don't know exactly what size or where the hole is located. It is typically located right behind the sunroof with a plug covering the hole in the headliner.
