Cadillac Repair: air conditioning, cadillac sedan deville, hello tom

Question
Hello Tom, trying to check the wiring to the A/C compressor with a meter. Wire plug connector should read voltage? Also reading at the mail pins on compressor ohms or?. Also can I connect or jumper these pins to eliminate car wireing. Reason I dont see the compressor start turning when my son turns on A/C. I heard some like this years ago. Oh, sorry the A/C does'nt blow cold air blowing at all, is why I started snooping under the hood.Fuses, that one relay are Ok.

Answer
you should have battery voltage at the compressor DARK GREEN wire. If NOT, You will have to e-mail me at: onlineautohelp@msn.com for the location of the AC relay.

You need to have aset of AC gages to see that you have enough freon in the system when you jumper the relay connections.
