SUBJECT:
A/C SYSTEM DISCHARGED OR A/C LINE CONTACTS BATTERY CABLE
MODELS AFFECTED: 1989 RIVIERAS
Some 1989 Rivieras built after VIN 1G4EZ11C5KU411752 thru end of production may experience a condition of the A/C system discharged due to a
cracked or worn A/C line near the compressor, or an underhood knock on hard acceleration due to interference between the battery cable and the A/C
line near the A/C compressor. Use following procedures:
When repairing the knock on hard acceleration or when servicing the A/C line or battery cable, route the battery cable near the A/C compressor at the
front right motor mount. Refer to Figure 1. This should provide clearance to the A/C line when the engine is rocked on the motor mount.
^
The battery cable may be rerouted by loosening the two frame attaching clips and moving the cable as far to the passenger side of the car as
possible.
^
Reposition the frame attaching clips and secure them in the original frame holes.
^
Be certain that the cable assembly does not interfere with the accessory drive belt.
