Number 85-1-6 Date 3/85Subject: AIR CONDITIONING COMPRESSOR HIGH PRESSURE SWITCH & CUTOUT SWITCH WIRING REPAIR
1985 GRAND AM
FIGURE 1 - PRESSURE & CUTOFF SWITCH WIRING:
FIGURE 2 - HOSE ASSEMBLY:
Some 1985 Grand Am vehicles equipped with 2.5L 4 cylinder engine and air conditioning may experience a blown heater-A/C fuse, intermittant high pressure switch cycling or intermittant compressor clutch cycling (e.g., normal clutch cycles become too frequent or highly erratic).
This condition may be the result of the A/C compressor pressure switch wiring and cutout switch wiring shorting against the exhaust pipe.
To repair the condition, repair 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).
