A/C - Intermittent Cycling Or Blown Fuse

Bulletin 85-1-19

Date Apr. '85

Ref. No. 85-213-1


SUBJECT: AIR CONDITIONING COMPRESSOR HIGH PRESSURE SWITCH AND CUTOUT SWITCH WIRING REPAIR

MODELS AFFECTED: 1985 SOMERSET

AIR CONDITIONING ASSEMBLY:

Some 1985 Somerset vehicles equipped with 2.5L 4 cylinder engine and air conditioning may experience a blown heater-A/C fuse, intermittent high pressure switch cycling or intermittent compressor clutch cycling (normal clutch cycles only on wide open throttle or full turn).

This condition may be the result of the A/C compressor switch wiring and cutout switch wiring shorting against the exhaust pipe.

To repair the condition, correct the shorted wiring. Add a tie strap (P/N 3816659) and strap the wiring to the air conditioning pipe by the A/C muffler (See illustration).
