Chrysler 300c where is the door opener relay controller located?
2007 Chrysler 300C:
The majority of electrical system fuses and relays are housed in the two Power Distribution Centers (PDC). One is located in the engine compartment, combined with the Front Control Module (FCM) to form the Integrated Power Module (IPM). The PDC is located next to the battery in the rear of the vehicle. The PDC located next to the battery is replaced only as part of the body wiring harness.

Randy. It sounds like a bad connection at the back of the control head (Chrysler talk for the actual cd/radio, sat nav)
If you have the courage to gently remove the silver plastic surround with a blunt knife by prising it away from the dash ( this process is on the net with good photos) you will observe the 4 screws that hold the control head in position. I would unscrew them to get to the back of the unit and remove the 20-40 pin connector then push it home again a couple of times. You could spray a little Servicol electronic contact cleaner onto the connections. Be careful replacing the silver plastic surround as it is designed to break
My 2005 chrysler 300 ac worked great one day and just hot air the very next day
May need to be charged. Do you hear the compressor coming on? If not, put a gauge on the low pressure port to check pressure. If low, add r134a until pressure is normal. If system requires frequent refills (more than once per year), have it tested to find the leak. If the compressor is coming on, the problem may be the blend door not actuating properly.
