I have had an issue come up with my A/C. I have cold air blowing out of the two driver side vents, but the air coming out of the passengers sides is still warm and being in AZ this has become a need to fix quick issue. Does any one know the a/c workings of dodge trucks I have a 2003 quad cab.

 

low freon is the first thing to check

 

Either low refrigerant charge (hopefully) or broken door inside the HVAC housing...

Check AC charge first, as you have to pull the entire dash to get into the hvac.
