Water Leak Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I dont have any holes in the firewall or the channel on the firewall.

I'm guessing its the seal on the drip rail or the windshield, however the top of the dash is never wet.

Best solution to fix the drip rail channel? Silicone?

I wouldn't. 3M has a product just for that purpose.

I added a picture of where mine was leaking at the lower windshield seam. I cleaned all of the seams out and re-caulked them. It can also leak in at the antenna cable if it is not sealed good.

Thank you to all. I will wait for it to dry out here a little, been raining so much, and try your advice.

How many trucks in Cali, do you think, are sprouting leaks these days?!?
