Section: 1B
Date: December, 1988
Subject: PRODUCT CAMPAIGN 89C02 AIR CONDITIONING COMPRESSOR & CONDENSER HOSE ASSEMBLY INTERFERENCE


Model and Year: 1989 CHEVROLET ASTROS WITH AIR CONDITIONING AND 4.3L V6 ENGINES (RPO LB4)
TO: ALL CHEVROLET DEALERS

General Motors has determined that 1989 Chevrolet Astros equipped with air conditioning (RPO C60/C69) and 4.3L V6 Engines (LB4) may have the high pressure A/C line (A/C compressor and condenser hose assembly) contacting the positive stud boot on the rear of the generator. If this line causes the stud to push through the boot and contact the line, arcing can occur, causing a hole in the line and total loss of A/C refrigerant.

To correct this condition, it will be necessary to inspect the line for necessary clearances or damage. If no damage has occurred, the line will be relocated. If damage has occurred, a new A/C line must be installed and relocated. An estimated 10% of the vehicles involved will require a new A/C line and recharge.
