My 2005 STR for whatever reason does not want to blow out a/c. It will blow out really hot heat no matter what temperature it is at. i changed the DCCV and the control module twice. i don’t hear the a/c compressor turning on but i don’t think i have any refrigerant but that wouldn’t cause me to get heat in all the temperatures. Please help

 

Have you tried driving down the selected temperature until LO is displayed? This bypasses most of the automatic controls.

Please see my troubleshooting guide for specific steps to take:

Work through post #2 first to make sure the DCCV is responding properly. There's no guarantee your new DCCV is good, so be sure to test it. You will see some fuses to check, too.

Once you get that sorted out, see post #5 for a lack of cooling.
