The car in question is my 1993 940 turbo wagon. I bought this car dirt cheap with some issues mostly electrical.The prior owner liked togle switches apperantly and I don't... Prob is as follows. The a/c was working on all speeds,but I would have to flip a switch he rigged for the compressor to switch on. Obviously I removed it and now do not have a/c. How can this be correctly repaired,please ?

 

Well, hard to say exactly other than to get in there and fix whatever it was that made the previous inventor hook the toggle, most likely the OFF/ON A/C switch on the control panel. You'll need a new switch, and replace it and wire it correctly. I'd get the switch from a junkyard.

 

Thanks,that was going to be my first attemp.

 

Also check the solder joints in the controller they are known to go bad all the time.
You can resolder the joints and usually be good to go.
