Normal Operation
The passenger seat control switch is supplied battery voltage and ground. When pressed, the seat control switch supplies voltage and ground to a power seat track motor or power recliner motor to move the seat or backrest to the desired position. There are 3 power seat track motors that combine to move the seat cushion horizontally (forward/rearward) and vertically (front up/down and rear up/down). There is an additional motor in the power recliner mechanism to move the seat backrest forward and rearward. If a new motor needs to be installed, it is necessary to install an entire power seat track or power recliner mechanism.
