Afterblow Module Operation:

The afterblow module will enable the blower to run at high speed for five (5) minutes. It will do so approximately fifty (50) minutes after the ignition has been turned off, provided the compressor had been engaged for four (4) or more minutes during the most recent ignition cycle. By doing so, the evaporator plenum and core are "Dried Out", reducing the chances of a recurring A/C odor.

AN AFTERBLOW MODULE WILL NOT REMOVE EXISTING A/C ODORS. REFER TO AN APPROPRIATE PRODUCT SERVICE BULLETIN FOR CLEANING/ODOR ELIMINATING PROCEDURES.
