High Pressure Sensor / Switch: All Technical Service Bulletins
Air Conditioner - Inoperative
Number:
91-433-1D
Section:
1D
Date:
OCT. 1991
Corporate Bulletin No.:
131211
ASE No.:
A7
Subject:
AIR CONDITIONER INOPERATIVE
Model and Year:
1991 CORSICA/BERETTA WITH 2.2L ENGINE
Condition:
A/C high-side pressure switch connector becomes partially disconnected, or will not stay connected, causing the A/C to be inoperative.
Cause:
Due to the orientation of the A/C hose during assembly, the switch connector may contact the generator brace, with engine movement. (This movement
occurs during engine acceleration/deceleration.) The combination of the connector making contact with the brace, and the engine moving, may partially
"unplug" the switch. Refer to Figure 1.
Correction:
Recover refrigerant and replace the hose to condenser inlet line "O" ring, using the proper handling procedures provided in the Service Manual.
