DESCRIPTION
If a customer complains of "poor air conditioning cooling performance" or "air conditioner doesn't work", it may be caused by the following condition:
Refrigerant R-12 may leak from bolt area which secures the hose assembly (block fitting) to the compressor cylinder head. This is caused by pin holes in
the aluminum casting, between the bolt hole and the discharge port.
To determine if a vehicle needs to be inspected for leakage, confirm the following:
1.
Check if the vehicles are within the following VIN range:
JM1FC33**H0500001-JMIFC33**H0543108
2.
Check if a yellow mark has been painted on the compressor as shown in illustration. If so, compressor has already been tested for leakage by the
manufacturer.
