I have a 2003 mpv. AC works great going down the freeway. When the car is stopped idling the AC does not get cold. As soon as you take off it begins to get cold again. Works great at highway speed. Dealer installed a new AC compressor saying it was not pumping at idle. I had checked the freon already with my gauges. Charge was good but pressures were a little high because I believe I did not have air flow like I should over the condenser. Now after replacing the compressor the dealer says it still does not work properly it needs a new fan drive. I'm not from familiar with the fan drive. I've also replaced the fan control module. My feeling is the compressor was good all along and the issue is with airflow in the Fan's not working properly. Thoughts?
