Abstract
An HVAC system for a vehicle preferably utilizes a control panel which encodes operator request signals at the control panel prior to sending those signals to a driver module. In this way, complex wire harnesses are not required. A most preferred embodiment includes a wireless connection between a control input and a driver module for receiving control signals and driving appropriate components on the HVAC system. The control signals are preferably transmitted over a wireless link through RF technology. Alternatively, infrared signals may be utilized.
