You are going to have to tear it apart, chances are something in the operating mechanism is broken and until that is fixed you are stuck.

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 .

My sunroof is stuck open its acting like it wants to close but goes back


If you have a 740 with an electric sunroof, when the roof is in the fully closed position you should be able to push the closed switch again and have the rear of the roof pop up to the 'vent' position. If you have a manual roof, after it reaches the closed position you feel a bit of resistance; you then continue moving the crank in the closed direction and the rear of the roof should pop up to the 'vent' position.
If your roof does not move at all, you must NOT pry up the rear edge manually as there are cast tracks at the rear of the panel that hold it in place and you will break, bend, or damage the tracks, roof or the panel.
Most likely it is out of alignment and too tight for the minimal leverage applied by the motor to move it, as well as being thoroughly gunked up. The secret to lack of motion is most likely binding in the up and down motion of the panel. If manual, try moving the crank back and forth, bearing in mind that the first motion the roof makes is that up and down motion at the rear of the panel. If there is resistance to the crank motion immediately, there is 'likely' to not be any damage in the screw mechanism, just binding of the panel in the roof.
If nothing moves as you move the crank towards 'vent', push up gently through that small rectangular opening inside the headliner on the rear of the panel to help it along, by just pushing it free of the roof. The tracks at the rear of the panel move the panel up and down, either to pull it down before retracting or to pop the rear of the panel up for the 'vent' position, and if they are damaged or too gunked up, they will resist opening. The device that is connected to the motor/crank via screw cables slides back and forth in these tracks, raising and lowering the panel, which will not be possible unless you can move the crank/motor. Try to get it high enough to be able to peer inside the roof from the outside to unhook the headliner clips - once you get those, all is revealed and you will be able to see why your roof is not functioning properly.

How do I fix the sunroof that wont close


Sounds like the timing is out. Pull the headliner down enough so that you can get to the motor. Close the sunroof and allow it to stop where it wants to. Then remove the bolts holding the motor on, pull the motor out of the way of the gears and push the sunroof closed. Then remount the motor. It should work correctly after that.

My old mercedes w115 220 d (1974) manual sunroof is not closing. I don't know if there is any part of the sunroof missing beacuse the car was on a major reability program and I forget the pieces of the...


There's not a heck of a lot to the manual sunroof. I suspect some sort of debris in the track.
First off to remove a sunroof you open it all the way, looking down from on top of the car you will see the two chrome tracks on either side. They are healed on by two screws (there is a third adjustment screw on each side - it is obviously different and not holding the track down - don't mess with it -- or perhaps this is your problem...)
Remove the screws and the top to the tracks (they will lift right off) then slide the sunroof mostly closed and lift it out.
Now look into the tracks - back into the roof. Is there anything there that ought to not be there? Remove it - this can be challenging since it's narrow - a shot van and the biggest pice of tubing that will fit in there might do it for you.
Lube up the track with silicone lube (oil or grease will stick to dirt) clean the 4 feet of the sun roof. Notice the two rollers at the back these love the sunroof in place within it's open and push the back up when closed. With the roof out check that they move easily when you turn the handle.
Now back to the car - notice the two adjustment screws, they lift or lower the back of the track - perhaps you turned them when you were removing it the first time. In any event if they are up too high the roof won't fit (the wheels pushing out will try to push the sunroof door out of the car) You can see the small wedge next to the track - the wheels will roll up this wedge to close the back of the roof - and it needs to be in a reasonable position.
Don't force it you risk breaking the handle, the connecting mechanism or those wheels and where are you going to get a new one?
So now you can put the sunroof door back into place. Slide it back and forth - it should move easily. Now try to close it. It should close easily if not try adjusting the wedges down (this adjustment should not have changed but I am assuming you inadvertently changed these while trying to remove the sunroof door - it you're certain that you did not do that then it's something else).
Good Luck,
Frank

Sunroof will not close


It could be the motor, get someone to keep the activator pushed down and try pulling the sunroof into position. Some times they can be missing the runners and just need a little pull, the sunroof runs on a grooved track and a grooved wheel marries to the track, if this doesn"t work see if you can gain access to the wheel, that may be worn but can be replaced.

Moonroof wont close all the way


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.

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


sounds like the metal deflector in front of the sunroof,is separated and caught in the roof mechanism, however there are other issues that can cause that condition, it can be anything from a bad sunroof switch to the sunroof tracks jamming, start with looking to see if there any obstuctions in the track..the sunroof mechanism can get costly to repair.

Sunroof stuck in the open position. can;t close.


The problem is probably the 'flap' of metal that's popped up, just above the where the handle is.
The runners/rails have undoubtedly corroded, and now there isn't anything to pull it down.
Luckily, as a 'Get the roof shut cos it's p*^%g
down' solution,,.
You can just hold your finger on the flap, to hold it down, in between the sunroof, and hole as you shut it.
Just remember to remove your finger Before you finish closing the sunroof.
Happy motoring.
