DeVille
The left and the right power seat system consist of the following components:
| • | The 4 reversible motors: |
| - | The front vertical motor |
| - | The rear vertical 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 vertical switch |
| • | The rear vertical switch |
The seat relay module receives inputs from the front and the rear vertical
switches simultaneously, when the entire seat switch is pushed to the UP position.
The seat relay module supplies 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.

the motor to run in the opposite direction. This action drives the seat backward.
These recline switches operate similar but independently:
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.
