This condition may be caused by the A/C compressor clutch diode legs becoming shorted to the harness. The diode was relocated about seven inches
away from the compressor clutch connector with the introduction of the pull-to-seat connector for the 1989 model year. To repair this condition use the
following procedure:
1.
Raise the vehicle.
2.
Remove the compressor splash shield as described in the appropriate Service Information Manual.
3.
Remove the conduit and heat shrink material protecting the diode.
4.
Test diode with a digital voltmeter. Generally, a properly operating diode can be re-insulated and returned to the harness conduit. Inoperative
diodes should be replaced using a 1 amp, 2000 volt common clamping diode, available at local electronic stores.
