Power Seat Switch: Description and Operation
Lumbar Support (With RPO Code A45)

LUMBAR SWITCH 

Battery positive voltage is supplied at all times to the driver seat lumbar switch from the SEATS Fuse located in the left rear fuse block. When the
lumbar switches are pressed they send a 12 volt signal to the MSM. The MSM then commands the lumbar motor to move in response to the switch
signals.
