Air Conditioning and charging system Troubleshooting 700 1991

posted by  someone claiming to be fixit 2003 on  Wed Apr 19 02:12 CST 2006 [RELATED]

With the engine running you should have 12 volts at one of the ac pressure sensor plug pins. If you do then shorting the pins together should activate the compressor clutch. If the clutch doesn't energize try connecting 12 volts from the battery directly to the clutch wire. That should make it engage.
