Durango 2WD V8-4.7L VIN N (2001)
Two small spring-clip retainers are located on either side of the insulated contact inside the bottom of the receptacle shell. These clips engage and
hold the heating element against the insulated contact long enough for the resistor coil to heat up. When the heating element is engaged with the
contact, battery current can flow through the resistor coil to ground, causing the resistor coil to heat.
When the resistor coil becomes sufficiently heated, excess heat radiates from the heating element causing the spring-clips to expand. Once the
spring-clips expand far enough to release the heating element, the spring-loaded housing forces the knob and heating element to pop back outward
to their relaxed position. When the cigar lighter knob and element are pulled out of the receptacle shell, the protective heat shield slides downward
on the housing so that the heating element is recessed and shielded around its circumference for safety.
CIRCUIT BREAKER
An automatic resetting circuit breaker in the junction block is used to protect the power seat system circuit. The circuit breaker can protect the
system from a short circuit, or from an overload condition caused by an obstructed or stuck seat adjuster.
The circuit breaker cannot be repaired and, if faulty or damaged, it must be replaced.
An automatic resetting circuit breaker in the junction block is used to protect the power window system circuit. The circuit breaker can protect the
system from a short circuit, or from an overload condition caused by an obstructed or stuck window glass or regulator.
The circuit breaker cannot be repaired and, if faulty, it must be replaced.
Circuit Breaker
1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker slightly, but be certain that the circuit breaker terminals still
contact the terminals in the junction block cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground.
3. With the voltmeter positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither terminal has battery voltage, repair the open
circuit from the Power Distribution Center (PDC) as required.
