1994 Windshield Leakage
So I have a 1994 f-150, (now with pictures in gallery, very sexy.) and I can't figure out where it's leaking. The top of the windshield leaks, but I can't figure out from where. I used the silicon sealent across the entire trim. could it be from elsewhere, or is this the only place..? should I just re-seal, and hope I got all the spots? It's just kinda made me scratch my head. P.S. Check the pictures in the gallery.
Thanks guys,
Ryan

My '91 did the same thing, I don't know if the interior trim is the same but I have a solid piece that covers the windshield and headliner and runs the width of the cab. Three screws and it will fall and hit ya! Take the chrome trim off of the windshield (carefully with flatblad screwdriver, stuff bends easilt) Get in the truck and have someone run a garden hose with low pressure slowly across the top of the windshield (from the outside) and feel for the drips. If you don't take off the interior trim, the water may come in from one side and if the truck isn't level, it will run down that trim piece and drip out the other side!
When found, use the liquide sealent that you can get at a glass store, sorry I can't remember the brand name. A few bucks a bottle, and it will stay pliable so that it will flex with the gasket seal in the windshield and prevent cracking.
Sorry for the novel

I had the same problem on my 90 F250. I took the silver trim off the top of the windshield and ran a bead of silicone sealant at the edge of the glass where it meets the cab. After the trim is reinstalled, you can't see the silicone and no more leaks.

Nope. Silicone sealant merely redirects the leak to somewhere else over time. Good temporary solution (like while on vacation, for example), but ultimately its going to leak again.
Best way is to remove the windshield using a windshield remover too (which is essentially a "E" guitar string with two key chain rings... you can make one actually). Remove all the pre-existing goo from the frame and the glass, then reseal it with motorcraft windshield epoxy. That is one item I really would get from the dealer. You'll never have to think about a windshield leak again as long as you own the truck. The windshield frame will rot out long before the motorcraft sealant drys out.
BTW, in a real pinch, I've even used bathtub chaulking (I discovered a leak in a car we had, while at home depot, and we happened to have bought tile chaulk. Pulled over, swadged some in, drove home the rest of the way. See, the leak was at the bottom of the windshield, resulting in a nice stream of water into my face, while driving.
Most unpleasant.

On my 94 caravan i removed the exterior trim and then the inside trim. Drove through a car wash and marked where the leak was. Once dried, i added some black door gasket sealer waited a few days for it to mold into the leak. It leaked the first couple of days then i parked it in the sun and its been good for about 8 months. I think a tub of sealer from the windshield repair shop would be longer lasting??? Leave the interior trim off the inside for awhile. Where is it leaking? You don't wont water in your Engine computer

it was without a doubt leaking only on the top somewhere... I ought to take off the trim, see if I can't pinpoint it. How do you go about taking off the silver trim? i'd be interested in actually sealing it for good. It hasn't leaked yet, but it did stop for a while earlier, and the previous owner chaulked it. I'm encouraged to fix it for good so I can get rid of that bead of chaulk along the top. It would look a lot better. Thanks dudes

Yea, I did the same thing you did. I eventually took the trim off and put silicone under the trim once I found the leak. That seamed to to the trick.

Removing chrome trim from top of windshield
When I removed mine, I just pried from the windshield side going up. The hardest part was getting the ends of the top trim that sit behind the two vertical pieces to come out without having to take the vertical pieces off too. Mine wasn't real difficult, as it most likely had been taken off before. You need to be careful not to lose the little L-shaped clips that hold the trim on as they tend to be a little springy. When you go to put the trim back on, postition the clips so they are sticking up away from the windshield and position the trim where it needs to be. Then the trim seems to 'snap' into place when you apply downward pressure. Hopefully I described it well enough to give you an idea of how it goes. I am also assuming the windshield setup is similar on these years of pickups?

Try looking at the factory seam sealed locations on the roof and driprail locations. My 95 has had the windshield replaced 3 times and I still have a leak at the top left corner of the windshield. I have the interior trim off and every time it rains, I get a leak coming in at the same spot. Drives me nuts. It looks like it is coming in from behind the urethane at the pinchweld, but I know that cant be it because I made sure the windshield guys cleaned and prepped that area especially. I even watched him put a load of goo in that area. This must have been an ongiong problem for the previous owner as evidenced by the silicone on the trim. I am going to reseal the gutters and seams and see if that helps. If that does it ,then its new carpet time.

Don't use silicone, this is a rookie mistake. Even a rookie should be ashamed of putting silicone on a car body. Check the paint and glass suppliers like PPG or Dupont and get the correct product for the job. Run some searches. 3M made good autobody sealants, I guess they still do.
The water hose suggestion is good, build on that.
