Howdy everyone.

I’ve got a 75 Glenbrook. 2 things I need to fix asap,, appreciate any ideas on either or both-

#1- major leak above the big back window- no leak one day, next day tons of water dripping down, appears to be in the center along the top, but not sure exactly where. I’m thinking of getting black caulk and applying on the black line that’s ABOVE the window framing (just below where all the paint is chipped away in the first 2 pictures here- http://www.cbabc.com/gmc/index.html
question- should I remove the existing caulking/ plastic, or put it on top of existing?

#2- kitchen lights/ exhaust fan became unattached on the side nearest the wall- best way to fix? pictures are #3 and 4 at the same website - http://www.cbabc.com/gmc/index.html


Thanks!

Best to remove old and replace with new. Leaks may also be from clearance lights or roof rack, if you have one.

JT,
Here's what I did. I cleaned out any old caulk that a PO had put in the groove. Then I got a pkg of the gray foam "backer rod" at the hdwr store. I got the size bigger than the groove. I then pushed the foam into the groove with a putty knife on the top and sides of the whole back panel. Voila, no more leaks.

Some people use vacuum hose - that works also. No need for caulking...

About 15 years ago when I got my coach I had the same leak. I measured the length across the top and down the sides I got one continuous piece of vacuum hose just slightly larger across than the gap in that seam. I started in the top center and worked across and down the sides, one side at a time. I pulled and stretched the hose as I installed it to make it slightly thinner as I filled the seam. Over time the hose will retract and fill any regularities in the width of the seam. I did not bother with sealing the bottom. The whole project took about 20 minutes to install.

The hose trick works well. I use 1/2" O.D. Foam backer rod. It can be
forced into the gap with a dull putty knife while pulling a slight stretch
on the rod. No sealer is used. It really works well.
