Customer: replied 2 years ago.
I can not get the compressor to come on to check Freon pressure but just will the gauges on 98 on high side and 88 on low side
Expert:  Brad replied 2 years ago.

Customer: replied 2 years ago.
No I don't
Expert:  Brad replied 2 years ago.
HI,
Here is the wiring for the a/c compressor:

The TIPM which is the fuse box under the hood controls the relay with an internal relay. I would like to verify you have the proper charge first, then if it still will not actuate you will need a scantool to monitor the low and high side pressure transducers and if the a/c is requested on.
I hope this helps, and if you need anymore assistance all you have to do is reply..
