| APaS09142020 | 2020-09-22. Service bulletin. VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM:COMPRESSOR; EQUIPMENT. Dealer Message - We've noticed an unprecedented demand for A/C compressors which at times has created a backorder situation. The majority of the compressors returned were analyzed and proven leak free. As you are aware, there is Warranty Extension for Civic Condensers (Service Bulletin 19-091) for a leak problem. This bulletin provides detailed information on how to use the Bosch ROBLD020 Dual Mode Refrigerant Gas Leak Detector which should be used to confirm a leak at the compressor. |
