Sealing up the Windshield

[Jim Stoltz]

Does anyone happen to know how the windshield is installed on these older motorhomes? There is trim on the inside secured with dozens of screws, but nothing on the outside. Do the screws on the inside have anything to do with the frame on the outside? I'd like to loosen the windshields up from the outside to get some caulk in there. The left one is leaking pretty bad. I don't want to just goop caulk along the top of it. It's ugly and not nearly as effective as getting it down in the frame where it needs to be.

Looks like your windshield is held in with a gasket. The best, most effective way, to seal this windshield is to replace the gasket and back fill with urethane from the inside at time of the gasket replacement.

Thanks. I was afraid of that. Not sure where I'd get a new gasket.

If you contact a local auto glass company they should be able to provide a possible universal gasket material that will work if you can not source an original.

I'll do that - thanks! Both windshields are cloudy around the edges. If it doesn't cost an arm and a leg I might have that addressed.

From 6 years of experience... I had a company windshield guy hot caulk the entire front glass , both passenger and driver side as Gone's have always leaked.  I've sealed around the trim with silicone. All the lights are sealed...  yup still leaks. I'm afraid to pull the inner trim off as due to water leaking who knows how long most of the wood is rotted out but still holding...  I tarp her up in winter.  My glass is starting to delam a bit at the bottom maybe 1" but not worried yet.

Mine's leaking just a bit left of center. Drips on the left fan on the dash.  My glass sounds like it's the same as yours. A bit at the bottom, about an inch in the corners. There's a fair amount of wind noise at speed, so I'm sure if I have to drive it in the rain I'll get soaked. While it's parked, it just leaks in that one spot.

I haven't messed with the clearance lights. It's possible it's running down from there, but it looks to be between the windshield gasket and frame.

Mine leaks exact same spot LOL.... I put a work towel over the fan when parked... the screws holding the fans are rusted at this point...  It drips a bit while driving at speed in pouring rain but not bad... I nave no clue where the water is coming in at this point other than having the glass completely removed and reinstalled which is $$$.  .  Also leaks around the triangular window drivers side too... same thing...  I've literally given up... trying to find it at this point..... oye vie.

Yes - driver's side triangular window leaks too. I just sealed the roof and took special care where the fiberglass nose meets the roof. It was obvious a lot of water was coming in there because the ceiling in both corners showed signs of it. After I sealed the roof, that triangular window stopped leaking (so far - knock on wood). Windshield still leaks though, so that must be the seal itself rather than water traveling from somewhere else.
