RE: a/c drain location
This is based on previous DMC Vehicles but I believe it is on the engine side of the frirewall when looking in from the hood, check somewhere along the passengers side about mid level, the Drain pattern for water is weird, but if you have a puddle of water and after a high humnididty day it would most likely be by the pax, front tire, inboard aft. I had Cherokee right in the above mentioned location. when you find the fitting, inspect it well,I had a wasp get stuck in one for about two weeks, and the water wouldnt drain overboard, and back drained into my carpet. I founf the offending wasp, evicted them most haste then had to take the front pax seat out for a sunny clear day t to dry the seat and caropet area. I would almost conclude that even with the rear and heat controllers are probably hooked to a common drain line Good luck if I can get soe pictres I will submit online.
