GlennWest Posted February 27, 2020 Report Share Posted February 27, 2020 (edited) I had a bad windshield leak. Think I posted on this some time back. New windshield as the old one was badly installed. It is now leaking again but in same spot it started before windhield was replaced. It is in direct line of top seam of cab on drivers side. This is the only spot that leaks now. I suspect that seal is bad. There is no sign of sealant on this seam. Suggestions.

SuiteSuccess Posted February 27, 2020 Report Share Posted February 27, 2020 Is it leaking down the glass on the inside or along the curtain rail? If along the rail try resealing the top seams in cab with expandable caulking. It stopped mine. If dripping down inside of windshield, try thin line of black silicone caulk along entire bottom edge of seal.

GlennWest Posted February 27, 2020 Author Report Share Posted February 27, 2020 leaking just above windshiel towards drivers side extreme about 3" from edge of visor. This lines up with cab seam.

rpsinc Posted March 1, 2020 Report Share Posted March 1, 2020 I have had this happen in windshield replacement. When damaged one was removed, the windshield opening revealed some rusty areas that allowed for typical sealant methods to not work, so it needed some attention by adding additional sealant. I also was able to treat the rusty metal areas with a rust reforming primer to perhaps extend the life of the windshield frame. Not sure how it worked out as I sold the truck a year later, but it never did leak after that install. Quote Marcel Link to comment Share on other sites More sharing options...
GlennWest Posted March 1, 2020 Author Report Share Posted March 1, 2020 That appears to be all fiberglass. I got the black sealent and added it to top of windshield. Not rained yet. That moulding is a bear to get back on.

Flying Finn Posted March 2, 2020 Report Share Posted March 2, 2020 Glenn, I had a leak in the bottom of the windshield seal on the drivers side. Learned the hard way that water had leaked inside the engine compartment running down the firewall and into the junction box that joins the engine and cab wiring harnesses. Was not a cheap repair. Half the pins were corroded resulting in some interesting problems. May not be an issue for you but worth a look. Brad Quote Link to comment Share on other sites More sharing options...
