System Operation
The seat backs are adjusted from the two different locations as follows:
•
The switches in the interior light housing receive operating power through the seat back
relay when the ignition is switched on KL 15. The GM controls the operation of the relay
and the switches provide the ground.
•
The switches in the “D” pillar receive KL 30 and allow seat back adjustment whenever
the rear tailgate is opened to gain access to the switches.
•
The adjustment motors receive power and ground directly from the switches.
