Hi there. My one of the sun roofs in my Hummer stopped working today (and it's about to rain!). It will go half way then just stop when I try to close it. I tried closing it manually but I'm afraid that I may break it. Do you have any suggestions? Thanks soooo much!
If you do not use the sunroof on a regular basis the water standing in the track fills the cable tube and causes it to rust. unfortunately the only way to fix it is to replace the entire sunroof track. they do not sell parts separately except for the motor. to test the motor remove the 2 screws in the cover the switch is attached to. slide the cover foeward and it will come off. leave the wires plugged in and take the 2 10mil bolts out of the motor and it will come off. then try the sunroof switch and see if the motor works. if so, you need a new track. if not check voltage to motor. sanders paint and body 34695

hi i'm not familar with your car but if you can wind the sunroof back so the sunroof is fully open look at all four corners where the sunroof sits into there should be at least 2 drain holes which can over time become clogged with debris, if you find them use some warm water and flexi pipe to clean the drain holes out. hope this helps
The seal around your sunroof glass isnt water proof. If you look at the sunroof opening from above there is a troth that goes all around the opening with drain tubes in the front of the troth that get clogged. Look close youll see them.you can blow air through them is the safest way
Probably too late for you, but I just "fixed" the stuck sunroof. I didn't want to spend anything and didn't care if it worked, I only wanted it closed. By taking the motor off, I was able to easily push the sunroof closed, then secured the motor back in place and it keeps the sunroof locked, closed. I tested the seal by running water over it, and all is good. Liquid Roof Coatings Application and Uses BuyLiquidRoof
Hi. I was having trouble with my sun roof on a 2004 Montecarlo. I had two issues water coming in and would not operate fully. I could toggle the switch and it would not move very far. this is what I found. I started to pull down the lining and saw that the motor was in front of the sun roof. I found the drain lines on the front side corners of the tray around the inside of the sun roof. I found that the tube ran down the pillar's and out between the door hinge's. I took them off and blow them out one was plugged up. That fixed the water problem. The roof would move with help from me pushing. I got it opened and noticed the grease was hard. I cleaned up the grease and removed most of it with WD40. Now the sun roof works good as new. I thought the water problem was because the roof was not fully closed but I guess it is designed to have water pass by the roof seal and have it drain away. I always noticed water under the car after a rain or a car wash but did not realize iit was the sun roof draining.
this was actually a common problem with the early models. you should take it back to the dealership where a technician will perfrom a "tsb" on the drain channels that run through the "A" pillar. they got pinched during assembly. best case it might be clogged with dirt in which case you can blow through these channels yourself with compressed air. they are located in the front corners of the sunroof channel while open. good luck.
