        If you can manually apply voltage to the pulley clutch and engage it, you’re probably looking at an electrical issue.

        First thing you have to do is confirm that the signal is being sent by whatever is supposed to send it. If it’s not there might be something outside of the AC system in fault that’s stopping it from engaging. Or there could simply be a broken wire or malfunctioning switch.

          Did you check the fuse and the relay?
