Mac cxu613 fan clutch

Recommended Posts

Hello, my name is Brian and am an a/c mechanic. I have a customer with a 2015 cxu613. The problem im having is with the fan clutch not engageing at all allowing the head pressure to sky rocket. I have ran the truck for at least 30 mins and have never seen fan engage. I do have 12v going to it but not sure which wire should have the 5 v computer reference signal. I believe im dealing with a bad fan clutch. Anyone have input that may be helpful to me?

The round "green" pressure sensor in the high side line is for the AC/fan clutch. Unplug and fan should speed up. However if the AC system has the "flashing box' APADS  system installed under the hood, then its a wild goose chase.
