Re: 2002 Grand Prix A/C Troubles
Unplug the connector at the compressor clutch coil and replace the fuse with a 10 amp-- if it does not blow- then you have a bad coil on the compressor--double check by doing a resistance check across the coil- should be 3.45 ohms cold...
If it still blows - then look in the wiring harness - especially at the inline diode-- although I thought the diodes were built into the coil connector by then-- if you can see it-- if the coil base has a "+" and a "-" on it then the diode is in the coil- not inline-- these are polarity sensitive- the ones with diodes in the coils-and they can't be wired backwards as older models could.... green is always positive- black wire is ground.
