Bonnie water leak.

Post by CHRIS904 »

Got into another project today. Found out my Bonneville has been storing water under the carpet foam. Driver side and two rear seats have water flooding in. Passenger front is the only dry area. Going to check sunroof and door seals. I have already sealed the trunk up.

Confirmed door seals leaking. Tried to do the water trick to driver door the seals won't bite like they used to. Going to use some weatherstrip adhesive and see if I can get them to fit tight.

Make sure the bead of adhesive is consistent. Otherwise, it may just act like a dam as water tries to flow by and ends up backing up over the seal.

Will do unfortunately they don't make any weatherstrip with the trim interior pieces. So we will see what happens.
