The rear window on my '99 Supercab leaks. I thought it was the cargo light so sealed it up good with silicone but still leaking. I have heard that the back glass is bolted in on these years.....any info??? or suggestions??? It is a solid glass (non slider) TIA

 

Yes the rear glass assembly is bolted on, according to the '99 Ford Manual.

1. Remove the back window garnish moulding.
2. Lower the rear portion of the roof trim panel.

Yeah it's held in with a bunch of nuts on my 99 RC, pretty easy to remove. Just take off the trim around the inside of the window and you'll see what holds it in. Once you get all the fasteners off then you might have to push the glass a bit to get it to come loose. The metal window frame will come out complete with the glass inside of it.

There is a seal around the window frame, this is probably what you need to replace. Go to the parts store and get "Windo-Weld" Ribbon Sealer, it's made by 3M. I forget the diameter but just get what looks like it fits in the channel around the window. To remove the old sealer you'll need rubbing alcohol and lots of time and patience. You'll need to clean both the window frame and the opening in the cab.

To put it back together just take the ribbon sealer and put it in the groove on the window frame. Cut it to length, make sure the ends meet nice and tight, and put the window back in the truck. Tighten slowly and evenly, a little at a time. If your glass doesn't quite set flush with the cab at first just put the truck in the sun for a while. Mine took a few days to fully seat but the seal worked immediately (tried with a hose) and after that I just went back and snugged everything up and put the trim back. Hardest part it cleaning the old crud off.

 

Thanks guys ......I will pull the trim and make sure that is where it is leaking!!!! Sounds simple enough to fix..........tired of the wet carpet every time it rains
