Ok, clarification, while she waits in the car, while I run errands, in stores etc. She has been disabled for awhile, so since its difficult for her to walk, she often waits in the car for me. The real point here is even at idle, the AC provides good cooling and does not cut out because the car is in neutral or at idle. Apparently the electric fan pulls enough air through the condensor and the radiator, for the AC to work well, as well as providing adequate cooling for the engine.
