Bought my 89 K5 durring the summer, so I didn't have the pleasure of having the funky smell at the time. Now that it's raining it's bad. I have sliding windows, the track selas on the inside are damp after it rains, so could it all be coming from there? The whole truck feels kinda damp and muggy, and I don't see any other leaks except for a small hole between the tailgate and top because the seal isn't good. One of the sliders is cracked so I'm going to replace them, should I put solid windows in there? and are they hard to install or should I have them installed? In LMC they have the solid wondows for $00 each, and $170 each with depp tint. I'll probably go for the $100 glass. Do I need to buy new seals or can I use mine?
