A/C drain line
My 95" is getting wet carpet on the passenger side. I believe it's condensation from the a/c that's not being drained away as there is no anti-freeze smell to it so it's probably not the heater core. But, I can't find where it's supposed to drain from. There apparently is no drain tube. Anybody know what I should be looking for?
Thanks, Jim

Interesting, GM must have discontinued putting them in the later C4's because my '87 sure has one---specifically for the evap core box drain, (in addition to the 3 cowl drain tubes). It's a fairly large tube, pinched at the end, under the blower motor. It's easily seen and accessed by removing the rh lower fender---and yes, they do get plugged.

If it has just started and you are sure there's no leaking from the weatherstrips, then it's the heater core.

Well, it may be more than a leak from a plugged drain,,,But! I got under and looked just above the fuel filter and there is a hole that was plugged with leaves. I think I will see if that takes care of the issue before I tear the heater core out.
Many thanks for the advice. Jim

If it's a small leak, it doesn't necessarily have the 'anti-freeze smell'. Been there, done that. http://finnshark.com/forum/showpost....postcount=2202 Don't mind the language. It's Finnish. But look at the later pics, you'll see how little the leak was with mine. That was enough to put a hazy layer on the windows and wet the passenger's floor. That hazy layer was easy to identify as coolant, since it felt very oil-like, but it could be wiped off with a damp cloth => water soluble ingredient = has to be coolant.
If it has just started and you are sure there's no leaking from the weatherstrips, then it's the heater core.
