Air conditioner control relay

Recommended Posts

I am new here so bear with me - I had a new compressor - all the things that goes with it put in my 1993 Cadillac Deville and replaced the relay - IF I run a hot wire to the battery it will kick on - other wise the compressor will not kick on - Is there another relay i need to change or what could it be - Thanks for any help you can give me :) - I am at shades@fidnet.com. Thanks...

If the air conditioner module (ACM) finds a problem with the system, it will throw a code and lock out the compressor. Here's how to get the code:


If there are no codes, then I would look for fuses first.

Yes, I was Jims_97_ETC before I changed cars.
