Power Seat Switch: Description and Operation

POWER SEAT SWITCHES
Battery positive is supplied at all times to the seat adjuster switch from the MEM T&T Fuse located in the rear fuse block. When the seat switches are pressed they send a 12 V signal to the MSM. The MSM commands the selected seat motor to move in response to the switch inputs.

LUMBAR SWITCH
Battery positive voltage (B+) is supplied at all times to the driver and passenger seat lumbar switches from the PWR SEAT Circuit Breaker located in the rear fuse block. Battery positive voltage (B+) is supplied at all times to the LR and RR passenger lumbar switches from the RR LUM/ANT Fuse located in the rear fuse block. All four lumbar switches are grounded through the switch ground circuits and G 302. The lumbar switches provide both power and ground to the selected lumbar motors.

SEAT ADJUSTER SWITCH
Battery positive voltage (B+) is supplied at all times to the driver and passenger seat adjuster switches from the PWR SEAT Circuit Breaker located in the rear fuse block. Both seat adjuster switches are grounded through the switch ground circuit and G 302. The seat adjuster switches provide both power and ground to the selected seat motors.
