'83 SC A/C problem
 

It is ouir first 80 plus degree day in Chi-town and I turned on my A/C....Nothin. Ran fine a few weeks ago when I uncovered the car for spring. Had refrigerant topped last summer.

No click from compessor clutch
No blower at all

checked fuse-OK
Checked voltage at A/C evaporator blower motor-voltage .46(?)

How do you check voltage at compressor clutch? Is the compressor clutch slaved to the evaporator blower motor so the compressor does not engage?

I suspect the evaporator blower motor. I assume the refrigerant connections must be opened- ergo let a trained pro take care of it, right?

Any other possibilities?

Is the system still stock? If not, then it might have a high/low pressure cut-off switch. If it does, and if you have a leak in your system, the switch will prevent juice from getting to the clutch.

Hi Glenn,
Did you also check the relay in the front?

Mine does the same thing when the freon is low.

Check the relay in the smuggler box, for a cheap fix go to rack shack and purchase an automotive relay. For a more expensive fix order a new relay from Porsche or our host. Unlrss they have NOS (new old stock) the new Porsche packaged relays are made in CHINA.

Yes it was a nice weekend in Chi-town. Did some quick maintenance on my 82SC Targa. Drain and replaced the oil, and went for a drive with the A/C on.
