What causes an AC compressor to not engage?
If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.

How do you jump the clutch on a GMC Truck?
The low-pressure safety cutout disables the compressor if there isn’t enough refrigerant in the system. Attach the can to the low port, start the truck, turn the AC on high/max, jump the compressor, start to fill it back up, and it’ll stay running itself. Might need more than one can :imo
