I have a 2005 Dodge Ram 1500 SLT with a 5.7 Hemi. My A/C only works on high. The codenser fan was replaced and the blower unit and the blower motor resistor under the dash too. I even replaced the climate control unit in the dash from a Dodge dealer.
Would you have any idea of why the air conditioner only work on high? Thanks for your time.
Respectfully,
Marc
Is the problem that the blower doesn't work, or is it that the AC blows hot air unless set to high? By "high" do you mean the blower motor control or the HVAC temperature control?
The a/c condenser fan only runs when the climate control unit is on max a/c also the a/c compressor only locks in at that time too. What I mean by a/c on high is the the blower unit under dash board has to be on high or maximum speed.
