I have a 2001 Jeep Wrangler that I am having problems with the heat. It blows HOT air but I am having problems with the selector switch (defrost, feet, vent, etc) It blows the air at the correct location as long the the jeep is at a dead idle, but as soon as you add any throttle, it will only blow air on defrost (at the windshield). Does anyone know if the doors on these this are vacuum controlled or electrically controlled or, or, or....
Any help would be apprectiated.
