does anyone have a picture of the sunroof drain hole location? I have a leaky roof when I go through a high pressure car wash and the water runs into the cabin through the open/close switch area. Thanks in advance for any help.

thanks shmoo....

 

You are welcome. Glad I (we) could help.

 

Are you sure the leak isn't coming from the antenna? It sits right above the switches, and you would probably notice any water leaks around the sunroof area first, if the leak was related to the sunroof.

 

Maybe it is leaking around the antenna. I'm not sure. I think I'll just avoid the high pressure washes....

 

Found this image, there appears to be a third drain line.

I always figured there had to be a rear drain, although I don't know how you could reach it without taking the whole sunroof apart. My 2 front drains were very clogged up creating a flood in my car whenever it rained.

 

I checked with the dealer and there are drains at the rear corners, each side. You can see the drain lines in the spare tire area. They drain thru the rear panel below the covering around the rear hatch latch. I passed air thru the lines but nothing changed. The lines connect to the sunroof assembly at the back corners just like the front. It looks like the headliner must come down.
Any better solutions are welcome. Please, I haven't fixed mine yet!!
If your drains are disconnected at the sunroof you will also have a moist smell from the front seatbelts.

 

Four drains as per Chevy parts dept.
