Lumbar Supports

With bucket and split bench seat combinations, each seat incorporates a power inflate/deflate pneumatic system for changing the contour of the seat. Ground is supplied at all times to both Power Lumbar Support Switches. When the Power Lumbar Support Switch is closed, voltage is applied, and current flows in the corresponding direction through the Power Lumbar Motor.

With a bench seat, one pump and pneumatic system is used to supply the seat lumbar supports. Individual control switches are incorporated into each side of the seat to change the seat contour.
