92 Park Avenue

[pbh3]

Got this well maintained 92 Buick Park Avenue from original owner. It is in pristine condition in and out. However, when I looked inside the trunk to examine the spare tire, discovered a rusty muddy pit. Cleaned and dried interior and left trunk empty. I drove it recently when we had a good rain and afterwards looked inside and the tire well contained at least a quart of water. Any suggestions on where I need to look for the leakage?

Dry it out, get in the trunk with a flash lite and have some one soak the car down while you look for the leaks, strip out all the trunk trim first.

Thanks for the tip, will let you know what I find out.

I had the same problem on my 92 PA. Check the seal around the rear lamp unit. I sealed the leak with silicone.

You were correct. The leak was coming through both ends of the long black rubber strip that runs along the top of rear light units. It had pulled away from the metal enoug to allow water to run along the trunk channel and drain into both rear lamp units. We ran a bead of silicone along the edge of the rubber strip where it meets the metal and also removed the back light assembly and siliconed the seals around the lamps. For now, problem is solved.
