Lumbar Supports

Battery voltage from I/P Circuit Breaker #1 is applied to the Driver Seatback Lumbar Support Switch and the Passenger Seatback Lumbar Support Switch through CKT 2240. The Switches, which are grounded at G201, normally ground both sides of the Adjuster Actuator Motors. When the switch is moved to rearward position, battery voltage is applied to the motor through the LT BLU wire and the switch. The motor will rotate to increase the seatback.The Lumbar Support Motor will be grounded through the LT GRN wire.

When the switch is moved to the forward position, battery voltage is applied to the motor through the LT GRN wire. The motor will be grounded through the LT BLU wire and the switch. The motor will rotate in the opposite direction and decrease the Seatback Lumbar Support.
