2006 and up A/C Clutch Relay is controlled by the TIPM. It is internal to the TIPM. I'm guessing that your compressor clutch is not engaging, correct?

Easy stuff first.

When was the last time it worked?

Does the yellow light on the HVAC control head light up when you press the snowflake button?

Do you see any visual hose leaks or damage?

Do you see anything unusual with the condenser? Large rock damage maybe?
