A permanent magnet motor moves each of the power windows. A master switch on driver's door controls all windows and can lock out rear window operation (Dakota Quad Cab and Durango). Power is supplied from a circuit breaker in the junction block when ignition is on. A positive and negative battery connection to either of the 2 motor terminals will cause the motor to rotate in one direction. Reversing current through these same 2 connections will cause the motor to rotate in the opposite direction. Each individual motor is grounded through the master switch by a wire attached to the instrument panel reinforcement. Vehicles are equipped with an Auto Down feature. Driver's window can be lowered without having to hold the switch in the down position. Auto Down feature can be activated by pressing down switch past first detent.
On Dakota, inspect circuit breaker No. 20 (20-amp) in junction block. On Durango inspect circuit breaker No. 21 (25-amp) in junction block. On all models, junction block is located on left end of instrument panel. Inspect fuse No. 9 (40-amp on Dakota, 50-amp on Durango) in Power Distribution Center (PDC). PDC is located in left front corner of engine compartment. Inspect power window system ground circuit. See WIRING DIAGRAMS.
