AFTERBLOW ENABLING
Afterblow is a feature that dries the evaporator core by operating the blower motor after the engine is turned off. This reduces the amount of microbial growth that can create undesirable odors. The vehicle does not come equipped with the afterblow feature turned on. If the afterblow feature is required due to an odor concern, it must be turned on by reprogramming the HVAC control module, refer to Service Programming System (SPS) in Programming and Setup.
After the HVAC control module has been programmed for afterblow, the following conditions must be met for afterblow to operate:
- The engine has been turned off for at least 30 minutes.
- The ambient air temperature is at least 21°C (70°F).
- The A/C compressor operated for more than 2 minutes.
- The system voltage is at least 12 volts.
Once the above conditions have been met, the following sequence of events will occur:
1. The blower motor will run for 20 seconds.
2. The blower motor will be off for 10 minutes.
3. The blower motor will run for and additional 20 seconds.
