I had a friend with a similar problem. the gears in the motor are plastic they tend to wear down to the point they stop making contact. Have someone press the botton and you can pull on the sunroof in the derection to close it. This is what i did for my friend and it worked out fine.

How to install replacement sunroof motor on a 1999 Pontiac grand prix


Important: This sunroof system is timed from the factory in order to allow the actuator to shut off automatically when the sunroof window reaches a certain position. Use extreme care when removing the actuator from the sunroof module. This may cause the timing to be thrown off. This may damage to the sunroof. Anytime the actuator needs to be removed from the module, ensure that the sunroof window is in the fully closed position.

I have an 05 grand prix, my sunroof vents and closes but will not slide back, is it a switch issue or what might you suggest?


could be the switch, or the plastic gear track that pulls the roof back with the motor might be stripped, this happened to me on my 97 grand am gt

My sunroof wont close


This is alot easier to diagnose with a test light or power probe. First off, you need to check your switch and make sure it is sending power to the motor. Next, make sure the motor is getting that power through the wiring harness. If the motor is getting power but not moving you MAY need a new motor. Every now and again, I see something obstructing the track. Look down the rails for anything that is one side but not the other.

The sunroof is tilted open and won't close. When


Sounds like sunroof is stuck, motor can't overcome load. Cheap test: car off, interior light turned on try to move sunroof, does light dim? If yes motor is trying to move but can't. If light does not dim then motor not getting power.

My sunroof won't close, is it the fuse? If so,


If the sunroof only opens but does not close the problem is the relay or the motor itself, try replacing the relay of this does not work, try replacing the roof motor.

Sunroofs off track and wont close


If your indicating the roof is crooked, that's odd... The roof slides along a channel actuated by a coiled cord.

Both of the cords pass along a gear attached to the Sunroof motor which pulles the cord tooth by tooth, impossible to go crooked unless really jammed or tampered with.

There are two plastic wedges that drop into the plastic slides on the sunroof (the plastic slides are behind the more forward metal slides.)

The plastic slides control the tilt of the roof when moved independantly. The plastic wedges join them.

If the roof moves too far back, it is possible for the wedges to stick up and jam the roof open.

This should never happen, but could if the two switches on the gear fail and no longer provide feedback to the controller indicating the roofs position.

Access to the Sunroof motor requires you to drop the headliner.

To drop the headliner, the plastic pillar shrouds need to be removed front and back, the seatbelt bolts in the middle secion need to be removed, the oh-**** handle, the front visors, and cabin lights.

Hope the info is helpful.

97 Grand Prix sunroof off track


My 97 Grand Prix sunroof tracks are offset. My driver side track is in the closed position, and the passenger side track is in a half open position. When the problem happened I was closing the roof and heard a hard clicking. It stopped working from that moment on. The tracks werent offset as much as they are now before I took the glass off. When I removed the glass, the passenger side track sprung back about 6 inches. The motor works, but the tracks only move about a half inch forward and backwards. Its cable operated and my guess is that one side jumped the track or a gear or something. Anybody help?
