Turned on the A/C the other day clutch engaged and then quit. Usually means the refrigerant was low. I attempted to recharge it today and the unit would not come on at all so, it would not accept the refrigerant. How can I recharge if the unit will not turn on. Any ideas or thoughts? I plan to check electrical connectors next, I disconnected them recently to move the wire harness out of the way doing another repair. It's 24 degrees now and it's dark. I'll trouble shoot further another day. Just wanted to know if anyone had any ideas.
