HVAC Module (K2xx)

Heating Ventilation and Air Conditioning (HVAC) module programming for GM “K2xx” trucks/SUVs. Exclusively available from CCE, this programming will allow you to customize parameters in your vehicle’s HVAC module and add new features as well!

You must already own an AutoSync third-party programmer device (google "AutoSync") first before purchasing this programming.

NOTE: Your vehicle must have IO4/IO5/IO6 radio, this programming is not supported on IO3/IOB radios.

• Program auto heated/cooled seat options based on driver memory setting (from the factory, options will NOT follow driver seat memory setting).
  
• Configure default startup temperature zone settings based on driver memory seat setting (default to single-zone 'sync' mode at start up, dual zone separate temps, or remember last setting)
• Configure remote start HVAC settings (if the HVAC will default to max hot, max cool, or whatever you left the setting at when you shut the vehicle off)
• Enable automatic front windshield defrost feature that will automatically select front defrost at startup when the outside air temp and humidity are within the range that could fog up windows.
• Rear HVAC zone (SUV only!) default startup settings (rear HVAC off, rear HVAC mimics front settings, last known settings at shut down)
• Add HVAC afterblow feature (automatically continues to run the HVAC blower motor for a period of time after the vehicle has been shut off/doors closed, to prevent musty smells)
