Why isn't my compressor getting fire to it?

@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.

Here is the complete HVAC part from the SM Caliber HVAC and here is the wiring diagram for the same Caliber HVAC Wiring
