Good morning, the A/C condenser is not engaging. Do you know where the A/C relay is in the vehicle listed above four wheel drive with rear A/C?

Good morning,

I attached the location of the relay in the relay box for you.

I doubt it is the relay. You need to check the Freon pressures to be sure you have the correct pressure for the system to work.

I attached a wiring diagram of the compressor circuit for you as well. If you have a test light or voltmeter, we can do some testing to find the fault.
