I also put 12v to the number 3 pin with the wire clip put into the A/C and the clutch didn't engage. I've been trying to read through post on here but I'm not finding my exact issue I don't think. Is there something at the climate control that would stop the A/C from getting the voltage? Thanks guys
If I understand your post correctly you have provided the A/C clutch with 12v by connecting from the C106 connector inside the large plastic box that hold the RCM, PCM and the BCM. That small clip on the front wall of the large plastic box feeds directly to the A/C clutch, as I understand your post after directly feeding the clutch power it did not engage. Your clutch and or compressor is bad. You have stated you had power at both ends of the wiring between the C106 connector and the clutch connector. When you apply power through the C106 connector to the clutch it will engage; Double check that procedure and if you are certain the clutch did not engage, you have found your problem. You can see the clutch movement and possible hear it engage. Do that testing with the engine turned off.
The input to the C106 connector comes from the A/C control as ala_Xfire shows in his post.
You can easily run 12volts DC through the C106 connector when it is disconnected by simply using a wire directly from the positive post of the battery to the C106 connector. I have tested my A/C clutch using that method and the clutch did engage with the 12v that I supplied.
