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).
