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
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.

i had the same probmlem its coming from one of 3 lights is the center quick fix was to use clear silicon from wal mart .. also it can leak from the moulding near the corners of the windsheald but rare...
some cars sunroof regulators come with a couple settings in sunroof
1 the 30 degree back tilt
2 half open stop sun roof
3 full open sunroof
these are common on sunroofs
now lets look at what could be the cause
bad regulator or needed greased gears
track needs to be cleaned which can stick the wheels down
most sunroofed vehicle regulators or gear boxes you will find in the trunk way up by the wheel wells in that little compartment tight to get out
also there should be a manual crank for sunroof placed somewhere in vehicle i know for my bmw it was back in the trunk on the gear box you will have to call dealer or look in manual to find sunroof manual crank and how to close
recommend taken to the closes dealer and have them service your sunroof mechanicals and have it cleaned up
sunroofs like cars needs to be cleaned on a certain milelage interval so that it will work for a long time
