Ok, the Air Conditioning Compressor Clutch will not engage, so lets figure out why not. With the ignition key on, unplug the low pressure switch (clutch cycling switch) and place a jumper wire across the connector. The switch is generally located on the side of the accumulator. If the compressor clutch does not click in then you need to check for Battery Voltage at the connector. If you do have Power leaving the A/C Clutch Relay and heading to the compressor but not power at the clutch, then replace the wire between the two.
