Found it and appreciate the response. Talked to my buddy and he suggested simply tapping into the harness (somewhere?) and turn on the aux fan to high speed whenever the A/C is turned on. Reason being, as I sit at a stoplight on a 90-plus degree day (most everyday here in Phoenix :-), the temp of the blown air gradually increases.

In my business, I'm in and out of the car looking at houses with clients and car has no chance to cool down between houses and consequently cabin temp is not so good, which in turn doesn't make for happy clients.

What do any of you think of this idea and how would we go about doing it? By the way, I do admit I'm probably a bit low on Freon but how much does that affect this situation?

Thanks as always for your help! Mike
