Seat Track: Description and Operation
POWER SEAT TRACK
There are three reversible motors that operate the power seat adjuster. The motors are connected to worm-drive gearboxes that move the seat adjuster
through a combination of screw-type drive units.
The front and rear of a seat are operated by different motors. They can be raised or lowered independently of each other. When the center seat switch is
pushed in the Up or Down direction, both the front and rear motors operate in unison. On standard cab models the entire seat is moved up or down, on
quad cab models the seat cushion moves independently of the seat back in the up or down directions. The forward-rearward motor is operated by pushing
the center seat switch in the Forward or Rearward direction, which moves the entire seat in the selected direction on all models.
Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers must not be
allowed to continue, or the motors may be damaged.
The power seat adjuster and motors cannot be repaired, and are serviced only as a complete unit. If any component in this unit is faulty or damaged, the
entire power seat adjuster and motors assembly must be replaced.
When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat switch contacts to the appropriate motor or
motors. The motor and drive unit operate to move the seat in the selected direction until the switch is released, or until the travel limit of the power seat
track is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through the switch
contacts. This causes the motor to run in the opposite direction.
