The left and the right power seat system consist of the seat switches and the following 4 reversible motors:
| • | The front vertical motor |
| • | The rear vertical motor |
| • | The horizontal motor |
| • | The recline motor |
These 4 motors operate independently of each other.
When the entire seat switch is pushed to the FORWARD position, the forward input of the of the seat relay is grounded.
The seat relay module supplies battery positive voltage (B+) with a ground to the horizontal motor, in response to this input. In order to drive the seat forward, the motor runs until the switch is released.
The BACK position works similar to the FORWARD position with the exception that the voltage polarity supplied by the seat relay module is reversed causing the motor to run in the opposite direction. This action drives the seat backward.
These recline switches operate similar but independently:
| • | The front switch |
| • | The rear switch |
| • | The recline switch |
When the entire seat switch is pushed to the UP position, battery positive voltage (B+) is applied through the top switch contacts to the front and the rear vertical motors. These motors are grounded through the down switches, that are not being operated. The seat relay module supplies the battery positive voltage (B+) with a ground to both vertical motors at the same time in order to move the seat UP. In order to move the entire seat DOWN, a similar action occurs.
