ERRATIC A/C COMP. OPERATION - POSSIBLE POWER STEERING SW.
Model(s): 1985-1987
Bulletin No.: Chevrolet 87-195
Date: 07/15/1987
Some 1985-1987 Cavaliers may experience erratic A/C compressor operation. This condition may be caused by a corroded power steering pressure switch. To diagnose this condition, disconnect the power steering pressure switch and jump across the connector terminals while the compressor is operating erratically. If the compressor stops cycling erratically, replace the power steering pressure switch, P/N 10041728. Should the compressor continue to cycle erratically, refer to the appropriate Service Manual diagnostic charts for A/C clutch control in Section 6E2 for L-4 engine equipped vehicles or Section 6E3 for V-6 equipped vehicles.
