Seats: Adjustments

CIRCUIT OPERATION
Lumbar position is adjustable on both power seats. Circuit F35 feeds the left and right lumbar adjustment switch. Identical circuits from each switch power or ground the lumbar motor to adjust lumbar position.

On either power seat, during LUMBAR FORWARD adjustments, the lumbar switch connects circuit F35 to circuit P106. Circuit P106 feeds the lumbar motor. The ground path is supplied on circuit P107 from the motor through the closed contacts in switch to circuit Z1.

For LUMBAR AFT adjustments, the circuits are reversed. P107 powers the motor and circuit P106 provides ground.
