Control Head





Control Head

Purpose and Operation
The control head is located in the center console above the radio. A control unit inside the control head receives inputs from the driver via the push buttons.

The control head then sends electrical signals to the components to operate the system. The control head contains a memory which stores the set temperature when the ignition is turned off.
