So i notice over the weekend how the front plastic tab on my side roof lights was broken i went a got some clear silicone to seal around the cables but did not get a chance to do it and we got some rain yesterday so woke up to see the water coming in ;-( .....

 

At least it wont cost much to fix it. Wait Do you have to buy a new light? Those are kinda pricey from GM.

 

Ill see if i can get it of another truck . Here (houston tx) i have a junk yard 10 mins away that always have 3 or 4 H2s under a roof that may have the lights , ill check on saturday ..if not than silicone will have to do till i order a new set of lights ....

 

Replaced mine with a new OEM (~$120).... Yeah, it sucked

 

Well we got some rain yesterday and the leak its back but i think that the water is getting in from somewhere under my windshield , ill have to wait till the weekend to take everything a part again and see if i can track it down ;-( ...

 

They're $100 for a pair give or take depending on where you get them. When I bought mine the driver side corner light had a broken tab. Thanks to the forums that was one thing I was looking for and made the dealership order a new pair before I signed the papers.

 

Now im wondering whats the part number for the base where the corner lights lay on ???
Look at this picture and notice the gap thats under the plastic piece .
Both sides are like this and i would like to fix it .
Here is another picture to give you guys a idea of how much water im taking

All the water sims to be coming in from under the dash on both driver and passenger side :-( ....

 

I had the same problem and couldnt find out where the water was coming from so i took it to a dealer and come to find out that hole where the wires go down is a drain for the roof racks and if they are clogged up the water will drain in past the seals all they had to do was blow air pressure not to exceed 35 psi or else you will rupture the tube. It only cost me 65 dollars to have all 4 of my drain tubes blown out and totally solved the problem you should try that first. I live in Pensacola Florida and we get massive down pours of rain at a time.

 

Jimmy thanks for the info ill try that and see what happends ... by the way i drive by pensacola a couple of times a year i have lots of family and friends all over FL my parents and i own a house in tampa ...
