Water in trunk REPAIRED
The cost of replacing the rusted amplifier and the radio module in the left side trunk well made me nuts!
I have been reading what I could about water intrusion issues on many threads.
There is a serious design flaw in using trim fasteners to hold the "drip trays" that channel the water between the fender and the trunk lid seal.
HERE IS AN EASY TEST to see if you have leaks at these fasteners and it does not involve removal of anything.
Open the trunk lid. Each of the trim fasteners is in a little recessed well. Using a cup of water and a straw (place the straw in the cup, cover the top end with your finger so the water stays in the straw) carefully fill each well.
The one(s) that are leaking will quickly wick the water into the trunk!
Because I had access to the trim clip removal tools, I pulled the clips and sealed each hole with silicone, reinstalling the clips while the sealant was still wet. I am sure that they could be sealed without removing the clips, just by carefully siliconing the tops.
