Air Conditioner

It seams like my AC runs all time, condensation drips even on cold days and when its just on the top vents. In my mind the AC should be running when on the *** is turned to 'AC' and to the 'window defrost'

Any Ideas?

The a/c should pump run in every position except heat, vent and off. That's just the way they did it.

So 'Heat' would be the floor symbol and 'Vent' would be the panel symbol? - It seams to me that it really drips more then most other vehicles in the parking lot could it be freezing up more then it should be and how would one tell if that is the case?

Defog uses the A/C since the A/C pulls moisture out of the air and thereby will clear a fogged window faster.

The a/c evaporator has a pressure switch that cycles the pump and is designed to maintain the evaporator just above freezing. If it were below freezing, it would not be dripping at all, it would be forming frost and eventually clog the evaporator and no air would get through.

It sounds like it's working normally. The amount of water dripping off usually depends on the relative humidity of the air it's cooling.
