Default Windshield still leaking

So Ive had my window resealed 3 times most recently back in January by the same people and it also ends up developing a leak over time. Last time I had it released because the drivers side corner leaked eventually ending to the death of my radio and thank got I have not bought another one.

Right now it leaks I'm assuming in the middle front of the seal as water drips down from where the RED lines are



Under the dash shots






Pulling back the dash pad no water can be seen. At this point I want to learn how to do it myself rather* than pay someone again to not do it right three times over the past 2 years (fixed under warranty each time).


What if I were to put a line of silicone across the entire line marked? Where would the water travel then? I kind of want to do it because its better than having water drip in the middle of the carpet and over a bunch of wires and such. As of right now I am going to keep my car clean every day so I don't have to wet wash it for a long time.

The channel in the seal on the glass side should be filled with Glass Bedding Compound. Push the seal smooth and straight, then fill the other side, the pinchweld side, completely with Glass Bedding Compound. Install the moulding immediately. It should take almost two complete tubes to do it, anything less and you are skimping.

Yeah all leaks have to be seal from the outside of the car not the inside.

you'll need something to pop the trim tabs free with then remove the trim.

Cut the seal on the outside of the glass

Push the window out careful like

remove the rubber seal and inspect and clean the channel you might find rust holes that go all the way through and contribute to your leaking issues. these will have to be repaired before any sealant is applied.

I think mustang monthly has a nice write up on the window reinstall procedure.

Also, spring for the FORD windshield gasket. I had the same problem. I tried 2 aftermarket windshield gaskets and kept getting leaks, went with a FORD gasket and have been dry for 8 years now.
