1992 and '93 Roadmasters built before VIN PR404608, with the Electronic Air Conditioning Option (RPO C68).
NOTE:
This bulletin includes an update to the 1991-92 Service Manual Section 1C.
CONDITION:
The air conditioning (A/C) system may become inoperative when the air compressor clutch does not engage. This may also coincide with the "Degree F"
or "Degree C" flashing and the "ECON" graphic illuminating on the Electronic Air Conditioning Control Display. A Diagnostic Trouble Code (DTC) 9
(low Freon) may also be stored in the microprocessor of the Air Conditioning Control Assembly.
CAUSE:
The above conditions will occur when the microprocessor in the Electronic Air Conditioning System detects low Freon. However, a false DTC 9 may be
set if the A/C control relay, high pressure cutout switch, or pressure cycling switch operate intermittently.
CORRECTION:
