A/C compressor not kicking in

It could be the relay. However, when you say the pressure is good, what are the high and low side pressure just to confirm we are okay? If you are not using a gauge set then let's see if we can rent them from a parts store because we have to confirm this before we go much further.

I attached the location of the relay and its operation. Let me know and we can go from there. Thanks

Good afternoon,

What is the high and low side pressures while the engine is off?

What are the pressures when the compressor kicks on, if possible?

I attached a wiring diagram for you to view. We need to do some checks. Do you have a test light to do some testing?

If you have power to the compressor then the compressor itself is bad and needs to be replaced.

So if you are saying that there is power at the compressor on the green wire as Roy shows then the compressor or at least coil is the issue. The relay, control module and wiring is all there to deliver voltage to the compressor when it needs to be engaged. If there is power there, then that is all working but the compressor is not.
