Afterblow Enabling

The afterblow mode can be enabled using the scan tool. The afterblow mode allows the blower motor to operate after the engine has been turned off. This operation of the blower motor dries the evaporator core, which reduces the amount of microbial growth which can create undesirable odors.

Use the following procedure in order to enable the afterblow mode:

1. Connect the Scan Tool.
2. Turn ON the ignition, with the engine OFF.
3. Build the vehicle with the scan tool.
4. Select Module Diagnosis.
5. Select Remote Heater and Air Conditioning Control Module.
6. Select Configuration/Reset Functions.
7. Select HVAC Afterblow Configuration.

When afterblow has been enabled by the scan tool the blower motor will operate at 68% blower speed for 2 min 30 s to 4 min after the engine has been in Key OFF for 30 min.

The following conditions must be met for the HVAC module to operate the afterblow:

* The outside air temperature must be at least 21°C (70°F).
* The A/C compressor must have operated during the latest key cycle.
* The engine must be turned off for at least 30 min.
* The system voltage must be at least 12 V.
