Manual Movement

The memory seat/mirror module receives the seat manual movement inputs from the LH seat switch. Battery positive voltage (B+) is supplied to the LH seat switch as follows:
^ On Oldsmobile vehicles, voltage is supplied from the RH rear fuse block I/IP 1 fuse via CKT 4O, ORN.
^ On Buick vehicles, voltage is supplied from the RH rear fuse block PWR STS circuit breaker via CKT 1340, ORN.

When a switch is actuated, battery positive voltage (B+) is supplied to the appropriate input of the memory seat/mirror module. When a horizontal, rear vertical, front vertical, or recline input is received, the MSM supplies battery positive voltage (B+) to the appropriate motor(s). This causes the seat or seatback to move accordingly.
