@wilbertorr the Caliber does not have a compressor relay. Power comes directly from the TIPM (PCM) I would check the fuses according to the wiring diagram and the owner's manual. The best way would be to get it scanned with a Dodge scanner to get the proper codes. There are a few things that can cause the no-power situation. Things like pressure switch, evap temp switch, Ambient temp sensor, or even a bad HVAC controller and many other situations can all can do this.
