I have confirmed that the refrigerant pressure switch is grounded and receiving power. How do I check the compressor relays and which relay is the compressor relay?

Hi and thanks for using 2CarPros.com.

The relay box is under the hood on the driver's side of the vehicle. As far as testing a relay, here is a link which describes how it is done and what you should find:
