if you are referring to the Compressor Relay (Magnetic Clutch Relay)
The magnetic clutch relay is built in the engine room junction block. Since the relay is constructed with a relay block that is in the junction block as a unit, it is impossible to disconnect the wire harness connecting with the relay block.If the relay has a malfunction, replace it with the junction block assembly wire harness together.

this sounds like the compressor is locking up
If compressor lock occurs during A/C operation, the A/C switch indicator on the A/C control assembly starts blinking
When this occurs, check for compressor lock (DTC 22) using diagnosis trouble code check, and then proceed to inspect the circuit or the component.
