OPERATION
The rear condenser fan suppression filter provides
protection against transient interference signals or
similar interference to the electronic rear condenser
fan circuits which can effect the performance of the
rear A/C control module circuits and radio reception
quality. The suppression filter for the rear condenser
fan consist of capacitors and inductance coils.
The rear condenser fan suppression filter cannot be
repaired and, if faulty or damaged, it must be
replaced. Refer to the appropriate wiring information
for complete HVAC wiring diagrams.
