Sunroof motor burnout while open - 1993 Saturn SC2

Posted by on

  • dawnhpt Aug 13, 2008

    We bought a 95 Saturn SL2 for my son. The sunroof was broken, but "magically" popped" open. When we tried to close it, it wouldn't budge. We opened it further, and guess what... it won't close, and it's all the way open. We took off the visors, and lights, and pulled down the headliner to find the manual so we can close it, and can find it. Can someone help? We just want to get it closed, and then seal it up.

On my 92, & I think they are the same from 91-96...

Looking up at the motor once the headliner is down, there's a white plastic (yellowed maybe) piece in a circular area. You stick a flat head screwdriver in there, preferably a wide one, & rotate the motor to close the roof.

If that's not quite it, look hard at that underside of the motor that's what you see. It will be there. If a flat head it's right, try other shaped tools like allen wrenches.

The motor is right to the rear of the overhead (map) light unit, maybe a 1/2" back from the lights, but buried behind that headliner. I just cut the liner from the map & I'll use cloth to cover the slices.

Pull thte headliner down and look at the motor. there is always a way to close or open it manually. Most are done with a small socket such as a 8mm. But always there is a way. Just remember to look before you start pulling the headliner down. It may be nessecary to remove items such as the light and even the visors. Hope it helps

SOURCE: subaru legacy sunroof wont open but motor turns

I had a similar problem when I bought my used 99 Legacy. The dealer was going to replace the sun roof, but never followed through. Mine would open every now & then. Once when I got it opened, I cleaned the rubber gaskets with silicon lubricant. Since then the roof has always opened for me. That was 3 years ago, and it is still works every time!

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 !

My sunroof has opened and now it won't close. Any clues?


You will have to remove the sunroof motor, and the sunroof glass. Then you can move the guide tracks seperately until they are in the closed position. Then you can put the glass and motor back in, remove the power source (fuse or disconnect wire harness) to prevent any accidental opening until you can get it fixed. Chances are that a guide track or cable is broken, this can be a costly fix. Do not take it to the dealership, they will only want to install a whole sunroof unit. Take it to a local shop that installs aftermarket sunroofs

My sunroof has opened and now it won't close. Any clues?


hi sounds like a faulty sunroof relay keeping the motor running it may well have blown the fuse or burned the motor out if you connected it back up and it doesn,t work at all but should be able to turn the sunroof back manually look on the sunroof motor there should be sometthing like a slot for a large screwdriver or a bolt head of sorts just wind it back and then check the relays and fuses if your switch is a electronic one make a make shift one and try [simple switch]on and off as this is delicate circiutery and the slightest short can destroy it best of luck yates210456
