1992 Cadillac Seville V8 Front Wheel Drive Automatic 225000 miles
The clutch on the A/C cpmpressor of my 1992 Cadillac Sevelle won't engage when I try to run the A/C. The " Auto" light remains lit on the dasboard display in the climate contrl section shows. The code on the diagnostic display shows a code 'A12' as 'current'. Although I tried to clear the code, it will not clear. I'm unsure if this code means that the refregerant is low and this is a pressure reading of the low pressure side. However, my ohm meter shows that the low pressure switch should be good as I get a continuaty reading when I test at the switch side with the sense wires unpluged. If I jumper the the sense wires at the connecter, it still won't clear. Also, when I test the ground wire to ground, it reads continuity. When I test for power on the power side of the connertor wire I also do read 12 volts! What am I misssing?
