ALL WITH REAR A/C
SITUATION:
REFRIGERANT LEAK IN REAR A/C LOW PRESSURE LINE
A refrigerant leak in the low-pressure line for the rear air conditioning may be caused by the upper spring perch of the left rear wheel hitting the low
pressure line and damaging the line.
RESOLUTION:
INSTALL PROTECTIVE SLEEVE AND/OR REPLACE REFRIGERANT LINE
Inspect the low-pressure line for damage. If evidence of contact is found but the line has not failed, install only the protective sleeve (LRN000003). If the
low-pressure line is significantly damaged or has failed, pre-install the line protector on the new line and replace the low-pressure line.
NOTE:
The repairs outlined in this TIB are to be performed to resolve customer complaint of the symptoms described.
