HEATED DOOR MIRROR OPERATION
The defogger relay switch is activated (ON) by turning on the A/C-ECU built-in defogger switch when the ignition switch is in the "ON" position. When the defogger relay is turned ON, power is supplied to the defogger and door mirror, and the heater of the door mirror (heated door mirror) starts operations. The defogger comes with a timer function and will automatically turn OFF the switch approximately 11 minutes after the defogger switch is turned ON. The heated door mirror operations are also terminated along with the defogger, at this time.
