Good afternoon,
Did you check the freon pressures? If they are low, the compressor will not come on.

I attached a wiring diagram of the system for you. If you have a test light, we can do some voltage checks to see why the clutch is not engaging.

As far as the relay, it cannot be accessed. It is part of a module.
Note: The compressor relay or A/C relay is located in the IPDM (intelligent power distribution module) and is not serviceable.
