Question about 1997 Pontiac Grand Prix

1 Answer

Sunroof not closing

I had this same problem after the gear slipped when accidently tried to open during the winter (frozen shut). When I tried to fix it, it opened too far and bent the support brackets. I had to have the window removed and just had it closed permanently. Replacing was an expensive option.

The position of the roof is determined by a pair of small electronic switches pushed up against a gear ajacent to the gear that drives the roof back and forth.

When "calibrating" the roof position to the logic (controller) You need to seperate the motor from the roof asy. command it wide open, then manually slide your roof open. Once close, use a flat-head scrwedriver to push the cords where the gear normally would the rest of the way to the alignment marks.

This is located near the back of the track, the two silver hatch marks on the plastic tilt slide should be just behind the track opening if I'm remembering correctly.

Once everything is lined up, it should work great. If your off by a tooth or two, pull the motor, and move it with the scewdriver, and try again.

It needs to be exact.

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.

Sunroof stuck


First off, you should leave it closed. At least you can drive it that way. The grinding could be the motor itself, or a gear inside that has rounded or broken teeth. Another possibility is that it has slipped out of a channel or track. Unless you're pretty handy this sounds like a professional repair job.

2005 Chevy Equinox sunroof problems


Some customers may comment that the sunroof will no longer respond to the control switch while in a vented, partially opened, or fully opened position.
Cause A software issue with the sunroof control module may cause the sunroof control module to incorrectly indicate a "closed" position, which may result in no power to the sunroof motor.
Correction Verify the customer concern. If a condition is present, replace the sunroof control module with a new sunroof control module, P/N 15847643. Refer to the Service Procedure in this bulletin.
Service Procedure
  1. Verify the customer concern by opening and closing the sunroof. • If the sunroof will not open , check the power windows. - If the power windows are also inoperative, check the fuse. If the fuse has opened, refer to Corporate Bulletin Number 05-08-64-004 to install 30A circuit breaker. - If the power windows are fully functional, refer to "Power Sunroof Inoperative" diagnostics (SI Document ID# 1392967) in the Body section of the 2005 Chevrolet Equinox or Saturn VUE Service Manual. • If the sunroof will open (or is already open), but will not close , proceed to Step 2.
  2. Replace the sunroof control module. Refer to "Sunroof Control Module Replacement" procedure in the Body section of the 2005 Chevrolet Equinox Service Manual (SI Document ID# 1196049) or Saturn VUE Service Manual (SI Document ID# 1710479).
  3. Open and close the sunroof in order to confirm that the customer concern has been resolved.

Volvo V7 '01 sunroof will not stop in closed position


I think I know the answer....your gear has slipped on the cable a few teeth. Set the roof to the desired closed position, flush with your roof. Then open the panel above the mirror by first prying off the switch plate and removing the two 10mm bolts holding the mirror. Remove the sunroof motor gear, or rather just lower it out so it is disengaged with the cables. Now connect the switch and hit the auto open button as if you wanted to open the roof with single flick of the switch. Now hit the auto close button (same button of course, but the single touch method). The motor will advance and stop to where it thinks the roof should be, closed, which it is. Reassemble the gear into the slot, test it if all good, replace the mirror and panel.
Good luck.
Manfred.

1998 Honda Accord Sunroof wont close all the way


I took mine in expecting to have it repaired and it turns out that it was just the screws along the left and right-hand side of the panel.  They were loose.  The guy told me that "it eventually happens" and that "it's only a matter of time".  He went on to say that "it shouldn't happen again".  So, check the screws on either side of the panel right where it's stopping.  I suspect that this is prohibiting yours from closing as well.

HTH!
