can a leaky sunroof be fixed?

[sarahinez]

I just bought a 2003 Denali XL. It's leaking all over after a heavy rain. Thru the passenger ac control , DVD, ceiling vents... I saw in archives that this is common in the O3, I'm just wondering if it can be fixed or if after service people are still having problems. Thanks!

yes it can be fixed, if you can find the problem. check all the drains to make sure they are clear and if you have any roof antennas you'll want to make sure they are sealed. i have run into many GM's with roof antenna issues. also, be aware of where you park, somtimes an incline can cause to much water to rush to one particular drain. to test each of the four drain tubes: open the sunroof and use a cup to poor water in one drain at a time(1 at each corner) do this until water hits the ground , if the drain channel floods before water hits the ground you have slow or plugged drain hose. i use compressed air to blow them out. good luck.

I like use alittle air pressure to clean sunroof drains.
