Bypassing Computer To Power AC Compressor.

Posted in Air Conditioning | Asked on Feb 1, 2012
Below is the question about Bypassing Computer To Power AC Compressor.,

I have a 199 Ford Windstar whose computer started acting up a week ago. A bunch of items on the Van stopped working including the AC. The blower still works fine , but the compressor doesn’t turn on. Is it possible to directly run a seperate 12v source to the compressor to have it turn on. I simply refuse to get a new computer, since I’ve only owned this car for 4 months and already spend $3500 on repairs. Will it work if its given power directly from any 12v source.

    Same question shame shame

  2. Frank M says:

    Yep,12v to compressor will work.

  3. Regerugged says:

    No. You will be bypassing controls as well. The A/C would run continuously.

  4. Lrs says:

    The reason AC is not working is usually because Ford has a “Fail Safe Mode” in the ECM. It shuts AC compressor down and usually
    ( if V8 ) will cut the engine power in half (runs on 4 cylinders). Get a
    OBD II Code Reader to check the status of your vehicles ECM.
    I would not recommend Bypassing the Computer.
