Annoying Leak............help! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello guys, I have this damn leak in the top right corner of my windsheild. When it rains, it leaks straight into my cab, inside the glovebox, and ending on the rubber floormats. Any answers to solve this problem would be wonderful!

Lift up the rubber and see if you can see the hole. If you can try to squeeze some weatherstipping adhesive in there. That might fix it for ya.

It might be leaking at the antenna. You should pull out the glovebox and look for daylight.

Could be from the drip rails too.That's where mine leaks at sometimes

I had exactly the same leak on my K20. I lifted the rubber on the window and stuffed it full of sealer but it did not stop. I started lookiing for a liquid sealer that is on the market that you can drip behind the seal but I never did find the name of it. Maybe someone else might know where to find it.

I'm not sure if this would be possible, but if you could sprinkle some powder around the windsheild seal and then hit it with the hose, if the powder gets washed away, you've found your leak.

If it is the windshield, you can try flowable silicone. It is made for that application.
I purchased some a while back from LMC.

It might be worth pulling the window and taking a good look behind the rubber seal. Had the same isue on my back window. The rust had eaten away part of the window frame whcih caused the seal to expand and create a leak. Flowable silicone might be a good temporary fix but make certain you fix the real cause before the damage becomes huge. It wasn't to hard to clean mine up, welded up some small pin holes and ground away all the surface rust.
