Got in the car this afternoon, turned on the ac (90 degrees in SoCal) and cold water (condensation) spat out the center vents. What's up thigh that? What do I need to replace/unclog?

probably the evaporator drain line. get under pass side of car, should see a little hose by itself on the bottom of the car. get a long wire and run it up the hose. if you get behind the dash where the evaporator is the hose comes off easily to clean

My car is a '91 S2... I crawled under the car and couldn't find anything that looked remotely like a drain hose, nor any place where one might have been.

Interestingly, while the right side of the car was up, the condensation (water) drained from the drivers' side onto my garage floor... not good. See the pix attached.
