AC clutch not engaging

Yes, I think that is it if it is the one going to the AC Compressor. The Red w/white stripe and White goes to the AC lock Sensor. If you are not getting any voltage when the AC is turned on then it is not being commanded or you have a wiring problem between the relay and the clutch.

Air Conditioning:
The A/C amplifier receives various signals, I.E., the engine RPM from the engine control module and coolant temperature from the engine control module, etc. When the engine is started and the A/C SW (A/C control assembly) is on, a signal is input to the A/C amplifier. As a result, current flows from IG1 NO.2 fuse to TERMINAL 2 of the MG CLT relay to TERMINAL 1 to TERMINAL MGC of the A/C amplifier to GROUND, turning the MG CLT relay on, so that the magnetic clutch is on and the A/C compressor operates.

If the integration control and panel detects the following conditions, it stops the air conditioning:
∗Evaporator outlet air temperature is too low.
∗There is a marked difference between the compressor speed and the engine speed.
∗The refrigerant pressure is abnormally high or abnormally low.
∗The engine speed is too low.
∗Rapid acceleration occurs

 

Jimmy what's the wire color that goes from the relay down to the mag clutch?

Instead of trying to troubleshoot everything at the relay, just go down to the clutch and see if you have power on that wire with the A/C turned on

 

The wire to the clutch coil is Violet.
