AIR CONDITIONING SYSTEM (for Hatchback) > Headlight Signal Circuit |
DESCRIPTION
The air conditioning amplifier assembly receives headlight operational signals to determine electrical load conditions. The electrical load condition signals are used for controlling the number of the PTC heater elements to be heated.WIRING DIAGRAM
