Cause
These conditions may be caused from the engine wiring harness chaffing against the mounting ring on the A/C accumulator. This contact may cause a
rub through to the wires enclosed in that harness, resulting in the above conditions. Damage to the harness may also result in several stored diagnostic
trouble codes.
Correction
Inspect and repair any damaged wires. Use the procedure listed below.
Note:
Do not install plastic conduit over the repaired area. Doing so may damage the A/C accumulator.
