i just picked up an 86 k5 blazer in mint condition on saturday for 2500.00 from an old man at a retirement village. i pulled back the rug on the passenger side floor just to see what was up, and the foam for the carpet was wet. any ideas where it is coming from, and maybe some tips of what i can do to stop it. the blazer has hardly any rust. tiny bit at drivers side tailgate area, and a tiny bit on drivers side where seatbelt fastens. thanks guys. and, great site!!!!
