Fog/Driving Lamp Switch: Description and Operation
The fog lamp switch is the bottom switch in the row of switches to the right of the radio.
-
Push fog lamp switch in to turn fog lamps ON.
-
Push fog lamp switch out to shut off fog lamps. The fog lamp switch is not directly connected to the fog lamps. In the ON position, the switch
provides a ground circuit for the fog lamp relay coil. The coil closes the relay contacts which complete the battery feed circuit to the fog lamps.
A separate circuit on the lamp side of the relay illuminates a Light Emitting Diode (LED) in the switch when the fog lamps are on.
