Question about 2000 Dodge Ram 1500 Truck
When accelerating cold air turns into hot air, usually when this happens I can decellerate and have cold air once again, when this happens I always hear a damper door close, help
The temp blend door is operated by a vacuum motor.At higher engine rpms the manifold vacuum decreases.Most manufactures incorporate a vacuum storage tank to compensate for this lose of vacuum.So it does sound like you have a vacuum leak to the ac control unit.There should be a vacuum line going through the firewall into the cab.Inspect this line for leaks.Good Luck!!!!
