Drip Drip Drip

I have a 1995 Chevrolet pickup truck. It appears that water is dripping ever so slowly onto the right front floorboard. :disappoin I believe it is only occurring when I running the A/C. Any ideas what is wrong? More importantly, any ideas on how to fix the problem? :shakehead

Sounds like the drain for your evaporator is plugged. You can see it under the hood on the passengers' side, along the firewall. It's a tube about half inch in diameter, and it's plastic, sticking out from the firewall. You can try to clean it out from there but be careful if you stick something inside that you don't get it stuck or damage the evaporator.
