ISSUE:
A/C cycling pressure switch readings during clutch disengagement (clutch off) may read as high as 27 psig for a properly operating switch with a normal
calibration of 22-24 psig during clutch disengagement. This may be caused by pressure reading being taken from a low side service charge port that is
not adjacent (within 177.8 mm/7") of the A/C cycling switch. A pressure drop in the A/C line results in high readings.
ACTION:
If the above condition is present, do not misdiagnose the A/C cycling pressure switch as faulty. The pressure readings above are considered normal.
Perform normal diagnosis as outlined in the appropriate model 1997 Service Manual.
