2012 5.0 sedan a/c clutch not engaging.

Anyone know how to test the a/c clutch? System has freon but clutch not turning pulley. Could it be caused by bad cooling fan?

I don't see how the fan would affect it. Check the connector to see it it is getting power. If yes, could be the clutch. If no, fuse or relay. Could be a bad pressure switch too, thinking you have low charge.

Checked gas pressure and its good. Found the TXV valve and there are 3 wires. Don't know what to "jump" to engage clutch. Anyone know?

system pressure switch that engages the compressor clutch could be bad or the connection to the switch could be bad.

Don't try to jumper it at the txv valve you can damage the connector, jumper it at the ac clutch relay in the fuse box. If you have power at the clutch connector but it hasn't grabbed, give it a gentle whack with a hammer handle. If it grabs then your clutch plate is spaced too far away from the magnet (Volvo has a big problem with this) if it doesn't grab but you have power running to it then your magnet is dead. if magnet is dead then it will have to be replaced. If the plate just needs adjustment look up a/c clutch zip tie hack. it will get you through for a couple months until you can get it replaced.
