I have a drip inside that appears to be AC related and wonder how to isolate and fix it. '82 GSL. It happens when I turn sharply after driving for a little while, all of a sudden cold water drips down on the passenger's foot. I presume it drips on the carpet when no passenger is there, because the carpet is wet sometimes too. I suspect AC because it's been particularly dry here in the Pacific Northwest.

Any ideas about what might be plugged or leaking?

 

There is a drain pan under the evaporator, and that has a drain tube. That tube is likely clogged. Hence, the water collecting in the pan will tend to spill out on a turn.

One method of repair:
Find the tube from underneath the car and use compressed air to blow it clear, back into the drain pan. It usually works.

 

Thank you for the tip. I'll try it out tomorrow morning!
