TECHNICAL SERVICE BULLETIN
SERVICE INFORMATION ON COUNTERCLOCKWISE ROTATION OF A/C COMPRESSOR CLUTCH DRIVE PLATE
APPLICATION
Model: 1996 Saturns
Group/Seq. No.: HVAC - 01
Corp. No. 681201
Bulletin No.: 96-T-01
Date: January, 1996
VEHICLES AFFECTED
1996 Saturns built after and including VIN TZ445870 and any vehicle serviced with the R134a service compressor (P/N 21031196)
PURPOSE
Internal changes have been made to A/C compressor built after the above mentioned VIN that allow the A/C system pressure to rotate the A/C compressor clutch drive plate in a counterclockwise rotation, after the A/C clutch is disengaged. This counterclockwise rotation is caused by the system pressure equalizing between the high side and low side after A/C clutch disengagement, and is considered normal.
Since the time for the high and low side system pressure to equalize is determined by temperature and pressure, the A/C clutch drive plate may rotate up to two minutes after A/C clutch disengagement.
