Would someone please tell me where to look for the A/C evaporator drain opening on my '78 Impala 305. The drain is apparently plugged since i get decent cooling but zero water seeping to the ground. Thanks.

Its kinda hard to get to, you'll have to loosen the inner fender wheel well to reach it, but its on the bottom left hand side if your facing the front of the car. Its a rubber flap and its a decent size so must have a lot of debris built up in there!

The second picture down there's a long flap right under where the blower motor sits https://www.gmbbodyforum.com/t46-leaking-heater-box-disassembly?highlight=Heater+box
