Vehicle idles properly at about 600rpm when heater off. When heater fan at max, motor stalls when slowing down to stop. Tach swings down to zero and shuts motor down. Starts immediately and idles at 600rpm. No problem if AC fan is off. Any experience or knowledge would be appreciated. Alternator? Idle control? Regulator?

Thanks for suggestions, before I start throwing parts at the problem.

Thanks. Currently, my AC compressor is inoperative and I have removed the fan belt. Heater works fine. I suspect something is amiss electrically as I had no problem prior to disconnecting compressor/belt..
