2006 Dodge Ram 1500 A/C problem
My A/C is stuck in the recirculate mode I'm thinking it is a vacuum leak issue, or is it a control switch problem? When I switch to the floor vents or a combination of floor and face vents it adjust just fine, even to defrost. But between recirculate and normal there is not change, and at idle when the truck is not moving the air gets warm. Any suggestions? Thank you.
Also, since I'm posting questions on my 2006 Ddge Ram 1500, my cruise control will not hold my speed. When I set the cruise control it floors the throttle like it is trying to get up to speed and it does not stop, I have to turn it off or hit the brake pedel to disengage the cruise control. Again I think it might be a vacuum leak problem?
When I switch to the floor vents, defrost or a combination of floor or defrost and face vents it does not change stays on face. I can chang to fresh air or inside air but will not change from face. can any one help me?
Sberntsen,
System operation is below.
OPERATION
Both the manual temperature control (MTC) single zone heating-A/C system and the dual zone heating-A/C system are blend-air type systems. In a blend-air heating-A/C system, a blend-air door controls the amount of conditioned air that is allowed to flow through, or around the heater core. In the available dual zone system, two blend-air doors are used to provide completely independent side-to-side temperature control of the discharge air. The temperature control(s) determines the discharge air temperature(s) by operating the blend door actuator(s), which move the blend-air door(s). This design allows almost immediate control of output air temperature(s).
The heating-A/C system pulls outside (ambient) air through the fresh air intake located at the cowl panel at the base of the windshield and into the air inlet housing above the heating, ventilation and air conditioning (HVAC) housing and passes through the A/C evaporator. Air flow is then directed either through or around the heater core. This is done by adjusting the position of the blend-air door(s) with the temperature control(s) located on the A/C-heater control in the instrument panel. Air flow is then directed out the floor outlet, instrument panel outlet or the defroster outlet in various combinations by adjusting the position of the mode-air doors using the mode control located on the A/C-heater control. The temperature and mode control uses electrical actuators to operate the air doors.
Impossible to know from here. Could be blend door mechanism broken as well.
