Was installing some 6x9'* into my Grand Prix, and I pulled up the carpet where the spare tire is, and I see it is slightly wet, tomorrow I am going to take the spare out and see if there is a bit of water down under the spare.
What is it with my cars and water? :/
I am guessing it is the trunk seal, or maybe from where the spoiler is attached.
Not totally sure though, I know seeing water in there made me feel cursed, lol
Anybody with a Grand Prix ever had their trunk get wet as well?
Looks like it is mainly on the right side, a bit behind where the tail light is, considering the area the spoiler is my first guess..

You don't like water in your trunks? I make you lamb!

If it was something like this I'd not mind at all!



I just cannot believe my lack of luck with water, stupid water always taking the path of the least resistance, lazy water!!
I am also a little angry that I had to remove my whole back seat, and four trim panels just to get the cover out of the way so I could remove my old 6x9'*
It was simple to swap speakers in my Park Ave!

Water sounds like your worst nemesis

You aren't kidding!
Been too humid and rainy, or else I'd have checked out the spoiler already...

Is this a GM trend? I guess the hose water tests are now again required with the GP.
Hopefully some poly sealant will cure the leak.
Best for you to find it now instead of fall/winter tho.
Hopefully fix is an easy one, good Luck finding source William.
