RAM 1500 Truck 4WD V8-5.9L VIN Z (2002)
Fig. 1 DR Power Seat Switch
PASSENGER SEAT SWITCH
The power seat on this model can be adjusted in eight different directions, up, down, front up, front down, rear up, rear down, rearward and
forward. The power seat switch on this model has an additional switch knob for adjusting the power lumbar support. The power seat switch is
located on the outboard side of the seat cushion on the seat cushion side shield. Refer to the owner's manual in the vehicle glove box for more
information on the power seat switch functions and the seat adjusting procedures.
The individual switches in the power seat switch assembly cannot be repaired. If one switch is damaged or faulty the entire power seat switch
assembly must be replaced.
When a power switch control knob or knobs are actuated, a battery feed and a ground path are applied through the switch contacts to the power
seat track or recliner adjuster motor. The selected adjuster motor operates to move the seat track or recliner through its drive unit in the selected
direction until the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the
battery feed and ground path to the motor are reversed through the switch contacts. This causes the adjuster motor to run in the opposite direction.
No power seat switch should be held applied in any direction after the adjuster has reached its travel limit. The power seat adjuster motors each
contain a self-resetting circuit breaker to protect them from overload. However, consecutive or frequent resetting of the circuit breaker must not be
allowed to continue, or the motor may be damaged.
LUMBAR CONTROL SWITCH
The power lumbar seat option includes an electrically operated lumbar support mechanism. A single two-way momentary power lumbar switch is
integral with the power seat switches. The power lumbar switch is secured to the back of the seat cushion side shield with screws, and the switch
paddle protrudes through a hole to the outside of the shield. The switch paddle is located in a shallow depression molded into the outer surface of
the seat cushion side shield that helps to shroud it from unintentional actuation when entering or leaving the vehicle.
The power lumbar switches cannot be adjusted or repaired and, if faulty or damaged, the seat switch assembly must be replaced.
When the power lumbar switch paddle is actuated, a battery feed and a ground path are applied through the switch contacts to the power lumbar
adjuster motor. The motor operates to move the lumbar adjuster through its drive unit in the selected direction until the switch is released, or until
the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor are
reversed through the switch contacts. This causes the motor to run in the opposite direction.
The power lumbar switch should not be held applied in either direction after the adjuster has reached its travel limit. The power lumbar adjuster
motor contains a self-resetting circuit breaker to protect it from overload. However, consecutive or frequent resetting of the circuit breaker must
not be allowed to continue, or the motor may be damaged.
