Motors

There are three motors that move the position of the seat These are the forward/back motor, rear height motor, and front height motor. Both height motors run simultaneously when the LH seat switch is operated to move the entire seat up and down. The recline motor moves the angle of the seatback.

All motors are reversible. For example, the seat is moved forward and back by one motor. When the memory seat/mirror module receives an input to move the seat forward, it supplies battery positive voltage (B+) and ground to run the motor to move the seat forward. When it receives a seat back input, the MSM will supply power to the same motor, but the voltage and ground will be on the opposite motor cavities. The voltage polarity is reversed and the motor will run the opposite direction, moving the seat back. All other seat motors are also powered this way.
