What you describe is exactly what happened to my PT Cruiser. There are sliding parts (plastic) that usually break on one side, my guess is due to dirt, etc in the area where they slide and lack of lubrication. Once this happens the only way to fix it is to drop the headliner, remove the sunroof from the car, and replace the parts that control the movement of the roof with new ones. The good part is that your motor and cable are most likely good because they are still moving the roof. Another good thing is that the repair is not terribly difficult; anyone reasonably mechanical should be able to do it. It is time consuming and tiring (working over your head), and a little tedious when removing and reinstalling the headliner. But it is very satisfying when you get your sunroof back again for way cheaper that what the dealer or a shop would charge and you'll be ready to go into business repairing your friends sunroofs if you want!

The actual repair of the sunroof is done out of the car and parts are available for a reasonable price from The Sunroof Doctor. I originally found them on ebay but at that time there was no listing for the parts for my car so I went to their website, sunroofdoctordotcom and ordered the kit for around 120 bucks. They don't have a listing for your Grand Prix but show kits for Olds Intrigues and Buick Century/Regals which I believe are the same body style. The kits come with detailed instructions and everything needed to fix the problem. By the way, I believe they use factory parts, they just do all the work and put the package together with the parts needed instead of you trying to figure it out at the parts counter.

And take it from me as a former dealer service advisor. DON'T just replace the parts on one side. YOU WILL regret it!

Good Luck.

From what I can find out, sun roofs are and "option" and are not in the diagram and is a pain to try and fix yourself. The track is most likely dirty and clogged up. Maybe someone has a better answer for you, but I would take it to the shop.

How do you repair P0446 trouble code on a 2000 pontiac grand prix gtp?


P0446 - Evaporative Emmission Control System Vent Control Circuit
Evap vent valve has only one purpose. It closes in order to seal the vent so the EVAP system can pressurize and ensure there are no leaks. Evap vent valve is usually supplied Batt. voltage with key on. The ECM's driver controls the ground, and when grounded, activates the valve (closing it). If the ECM detects a short to ground, and open,or a short to battery voltage on the control circuit, P0446 will set. Code also may refer to ECM detecting that EVAP system is unable to achieve or maintain vacuum during test.

Symptoms: There will be no obvious symptoms to driver, other than MIL illumination.

Causes: A code P0446 could mean one or more of the following has happened:
* Faulty vent valve
* Open, short or excessive resistance on Vent valve control circuit
* Blockage of vent valve
* Bad PCM

Possible Solutions: With a P0446 OBD-II trouble code, here are some things to try:
* Replace Vent valve
* Repair open, short, or resistance problem in control circuit
* Repair open, or short, or resistance problem in power circuit
* Replace PCM

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.

00 grand prix w/ 3.1 vent valve staying open white wire has no voltage and is not regestering as a ground. pink wire is putting out voltage constantly even when genisys switches valve closed (supposedly)...


This particular valve is supplied power all the time. The pcm toggles the ground to turn it on and off. While commanding it on and off try running your test lamp between both terminals to see if the circuit is working properly. If it is replace the vent valve.

97 Camry Sunroof will tilt, does not close all the way, will not


The side steel mechanism maybe jammed or worn, or possible foreign object jammed within the mechanism. Ii will require taking the sunroof apart, unless you can free it. Possible sunroof mechanism replacement. Hopefully this helps

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.

Leak!


There should be a rubber lining around the sunroof. That might need to be replaced, if not pull it almost completly off (dont pull it off all the way because its not fun to realign). Go to Lowes and pick up some clear sefl squeeze bathroom caulk and inject it inside the rubber fold.Then reapply. This actually worked on my buddies sunroof.
