running AC iin this heat while driving has become a priority

i noticed some water leaking from behind/below the dash onto the passenger side floor board, the water was cold, and the black box under the dash was also cold.
there was not alot of water, but more would run out around a lefthand turn.

I have a 91 NA
AC is cold
heat is hot

someone seems to think my heater core may have a leak

can anyone confirm or deny or provide more options, i don't want to rip the dash out to replace the heater core :P

look to see if your A\C drain is hook up that should be a small hose going throu the firewall... I dont think it is your heater core because if it was the water would be hot and not cold..

hmm well the drain tube appears to be attached and running through the firewall just fan, ran AC on way home today, but no leaks.
granted it started leaking after a long amount of time this weekend

Check your AC drain line, it sounds like your drain line is plugged or partially plugged and not allowing the condensation to drain out of the housing.
