Without Air Conditioning






Vehicles without air conditioning (A/C) have a conventional control panel with three rotary switches. Each flap for temperature control and air distribution is mechanically operated by two Bowden cables. The recirculating air function is operated by a switch which activates a servo motor.

The only difference on the control panel for vehicles with air conditioning is the extra switch for the air conditioning system.
