Has anyone else had this problem? My 2002 F150 leaks water through the back glass seal.

 

I haven't. Did you check your weather stripping on the exterior? I have had mine come loose on me, but that was from when I ran a Sirius antenna and didn't tuck it all back in tightly.

Oh and it could also be leaking from the 3rd brake light. I think that was more of an issue in the 04' and up but still a possibility. Take a look around there as well.

 

I just fixed mine 3 weeks ago. I used something called Butyl tape. I picked it up at Napa Auto Parts for like $25. I used this how-to to do it my self. I tried using that Window weld caulk type stuff but it didnt work cause i didnt use but half a tube and made a big mess. They say if you use that stuff to use a tube and a half, didnt know that till after the fact so i found that Butyl tape and it fixed it right up. Car wash and 3 heavy heavy rain tested approved!

 

Yes this was/is a very common problem with the '97-'03 trucks, mainly with the sliders, but have done some solid back glass as well. I'd say somewhere around 100 or so!!! But then again when you work in a dealership, you see stuff like that

Both F150's I have owned had leaky back windows. It is more common than you would think. Use the "how to" that spencer posted.

You need to do this:

I did it, didnt take long. no more leaks.

 

Mine leaked and i have the solid rear window. Did mine before the how-to was up and only cost me like 100 plus tax.

 

YEah it was 75 for a new window and 25 fo the butyl tape for me. Sold my old window for 50 bucks yesterday to recoup some of the cost

 

No need to sell anything. This fix should only cost you the price of new sealant... Like $12.00 Oh, and some good cleaner... so, maybe $20 total.

 

Yes, every F150 I've owned leaked... bad.

I replaced the butyl tape in my 1998 (slider) and it still leaked. I had to re-do the entire job but this time took the entire window apart and used black silicone (same OEM silicone to seal rear diffs) and then it was solid (new butyl tape, again).

I'll be doing my 2003 in the coming weeks (non-slider) and I'll start a thread. Besides new butyl tape, the window itself needs to be sealed. I try to post some pics.

 

thanks for all the tips. I actually just got an estimate from safelite to take it off and reseal it. $80 and a couple of hours is all it takes. saves me the time and headache and the $230 that the dealership wanted!

 

I am in the process of doing this repair. You should also seal the window itself. The picture below shows where you place a bead of silicone. This repair: the window and silicone (MotorCraft black, same used on rear diffs) was allowed to sit overnight to come up to 70-degree temperature. The bead was applied, and then left to sit overnight at the same temp (38-degrees outside today).

This site sucks 'cause you can only post one pic per post. (attachments???)

Be sure to clean the area that the new butyl tape will contact. You should use a citrus-based cleaner, followed by clean shop towels soaked in pure water to neutralize the chemical solution. Allow time to dry.

This is the last time I post a pic to this site... impossible! (30-mintues of effort per pic!)

Job is done. I decided to tint the window while it was on my bench. I'll let the tint cure for the week, then take the truck through a touchless car wash to test the repair. The tint was a lot of work, but I think worth it.
