Default Trunk interior condensation

I went out to my Bonnie this afternoon to pull a blanket I had in the trunk out. Well, I popped the trunk and reached for the blanket, and the whole thing felt wet. On one section of the blanket, it was actually frozen to the carpeting-type stuff that lines the trunk. I looked at the interior of the trunk lid and noticed it was covered in beads of condensation, so I assume the water was dripping down onto the blanket and that'* what made it wet. Anyway, I'm guessing this isn't normal, because I've never had a car that'* had moisture like that inside the trunk.... any ideas on what could be causing it and how to fix it?

Check your spare tire well. If moisture is ALREADY in there from another real leak, it will condense on the trunk lid inside surface. Make sure your antenna flange, trunk seal, rear window seal, and taillights aren't leaking.

Get the carpet kit for the underside of the trunk lid if you find no other leaks. This will prevent condensation. You can get this from the wrecker or www.gmpartsdirect.com

The GM part number is 25607543 for 92-95, and you'll need a few 20732399 retainers, too.

You're like a living, breathing encyclopedia. Thank you! I'll be sure to check all that out.

I had a body shop 'accidentally' leave mine off once. It started condensing right away. Solved the problem when I put it back on. I've also had the leaking rear window seal and taillight problem.

It is pretty common for the spoiler to leak where the bolts penetrate the trunk. Take each nut off and goop it up with sealant.

My trunk has been dry as a boneyard since my spoiler was put on.

Good to fix your leak before your lining starts to go moldy.... like mine did.
Well to be fair..... I think my lining was moldy when I bought the car.

I still hate that water drips/pours in due to the crease in the taillights when I open the trunk lid and it'* raining (or just washed).

Good point, this totally didn't occur to me. This is the first time I've noticed a problem like this, and my dad owned the car for three years prior to me and never had a problem with it... so no mold yet. But I definitely don't want mold/mildew stinking up my trunk in the future.
