Where is the A/C Condensate drain - The 1947 - Present Chevrolet & GMC Truck Message Board Network

on our square body trucks? I don't see any drain holes in the neighborhood of the HVAC apparatus on the firewall. I have factory A/C in my 83 C20.

It's under the evaporator housing

Between the halves of the evaporator case.

So, is it a small rectangular slot in the bottom of the case? Where along the bottom edge is it? I would like to make sure that it is not clogged up. I ran my finger along the bottom edge and did not notice a hole. I don't want to disassemble the case if I don't have to. Thanks.

Thanks. It looks quite small and I would not expect it to be that close to the firewall. I will check it out.
