Short history, only had the truck for a few weeks now. Bone stock 1995 Super Cab, long box 4 X 4. In cooler weather I typically run the heater control on mix 99% of the time (this is true in any vehicle I drive that has that feature). Had been noticing that the air conditioning dryer always had moisture on it after driving for a while. This morning, after getting to work, while walking to the building I looked back at the truck and notice water dripping by the right front tire. Upon investigation, found the water was dripping off the dryer. In my experience, this only happens when the ambient humidity is high and the compressor is running constantly. Which, finally brings us to my question. Why would the compressor be running constantly when on mix (heater/defroster) and I know the compressor cycles when on defrost?
