I have a leak from above the passenger side that runs down the windshield along the A-pillar into the dash and ends up soaking the carpet near the kicker panel (among other things I cant see taking water).

I have already:

1. Went to a glass specialist who confirmed it was not a leak in the seal of the windshield (9 months ago this company resealed my back windshield as this problem happens to many late F-150s).
2. Glass specialist (dealership also) said the drain holes from the sunroof might be clogged and take a air compressor to the holes to blow out any obstruction. I did that at my auto shop and poured water atop my truck and it drained as it should underneath the vehicle.

Now, another rain event later, I still have the same leak occurring in the same location previously mentioned. Any ideas what to do next?

 

I am not sure if my leak is from the same spot but I have been noticing a drip from my passenger side handle area when it rains.
I am planning to remove this door handle panel to see if I can find the leak. I am suspecting the windshield seal since I do not have a sunroof.
Any input into this issue would be appreciated.

 

For the first couple instances, your picture is what I had to go on. I only saw water drip from the passenger O-**** handle. For the last couple instances, I have been in my truck during the actual rain to discover most water will run down the inside of the windshield from the top all the way to the carpet next to the passenger kicker panel (through the dash).
I have since talked to the glass technician after I blew compressed air through the drain holes of my sunroof. His advice now is to tape off the sunroof and let it pour up top. With this action, I can conclude whether 1. the sunroof, or 2. something else is leaking.
He said he can reseal the windshield with the possibility of that being the problem and his original diagnosis to be wrong, but I would rather run the water test before giving the glass shop a couple hundred dollars for something that will not fix my leak. I trust the glass technicians work and advice as the previous job was done perfectly.

 

I taped off the sunroof trim and put a water hose over the top passenger roof of the truck. It wasn't long before water started pouring into my truck from the top of the windshield where it meets the clothed ceiling. most dripped from there with some to the passenger A-pillar handle as well. I am going back to my glass specialist to get the wind shield resealed. I am hoping this fixes the problem as I have no further ideas.

 

Let us know how you make out.

 

Late last nite I found one post on the forum that said the truck had a leak between the roof and the A-pillar after he took the O-**** handle and plastic molding off. I am going to check that out before I proceed to get windshield resealed.

 

just my two cents but i do windshields for a living and ford put a seam in the a pillar underneath where the windshields urethane goes. i have seen hundreds of these be rusted and allowing water entering the truck. you really have to look for it. it has been known to fry fuse boxes. when i did my windshield last month i found the same. i ground down both a pillars after i pulled the windshield and found the zig zag seam and the paint had lifted under the glue. after ground i primered it and smeared urethane over it and then ran my bead and set my glass. something to have them to look at if they pull your shield.

 

Thanks for sharing that info, I will definitely make a note of that.

 

It looks to be simpler then previously thought. Not sure if this pertains to what racincharger mentioned. I took off my sun visor and was able to peel back my ceiling to watch water come through about 6 inches of space where the seal of the windshield is. I taped a plastic bag over my roof for now. I want to do this job myself if possible. I dont think the whole windshield needs to be sealed. But I also want this done right. I am hesitant to peel the rubber trim off around the windshield. Will it go back in place after? When i peel that off, can i get to the resealing of leak?

 

where is it leaking? if its toward the metal it is usually rust that causes the leak. if is leaking between the glass and urethane. its primer failure of the glass. the best way to fix the leak is to use urethane on the inside. never use silicone. but you will need to prime it with the proper primer for the urethane. shouldn't cost much for you to go to your local glass shop and have them just patch it. they will have all the right stuff to do it and shouldnt cost much. usually we charge 30 bucks and sometimes free . if its rust the windshield will have to be removed to fix it. minor rust can be wirebrushed and primed. if its bad could be body shop time. hard tellin without seeing it.
