Town Car V8-4.6L VIN W (1997)
Cigarette Lighter: Description and Operation
An ash receptacle and cigar lighter knob and elements are located in the center of the instrument panel and in the rear armrests.
The cigar lighter knob and element has a low-resistance heating coil which operates much like the coil used in a portable heater.
-
When the cigar lighter knob and element is pushed completely into the cigar lighter socket and retainer, the circuit is closed and current flows
through the heating coil to the ground.
-
When sufficient heat is generated, the cigar lighter knob and element overcomes the spring pressure of the bi-metal retaining fingers and is
released.
