Normal Operation
The passenger seat control switch is supplied voltage and ground. When the passenger seat control switch is activated, voltage and ground is supplied to the seat track motor to move the seat to the desired position. The seat track motor moves the seat cushion horizontally (forward/rearward). If a new motor on the seat track needs to be installed, it is necessary to install an entire seat track assembly. There is an additional motor in the seat recliner mechanism to move the seat backrest forward and rearward.
