Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

Providing the AC system is properly charged and your pressures are with in specs then the problem can be caused by any of the following,

  • Air Conditioning (A/C) Pressure Transducer
  • Compressor Clutch
  • Evaporator Temperature Sensor
  • Totally Integrated Power Module (TIPM)
  • Totally Integrated Power Module (TIPM) Wiring
    In order to determine the cause you are going to need to do some testing. I have enclosed the steps in the link below.

    See the wiring diagram in this link for reference. The fuse to check are marked in this diagram along with there locations.
