Power Lumbar Seats

The POWER SEAT fuse applies voltage to the Power Lumbar/Bolster Switch at all times.

When the Lumbar Support Switch is pressed, current flows to the Power Lumbar/Bolster Compressor Motor from the POWER SEAT Fuse through circuit 86 (W/BK or BK/Y) and the Lumbar Support Switch. The motor runs since it is grounded at G400 through circuit 53 (W or BK) and the lumbar support inflates.

When the Side Support Switch is pressed, current flows to the Power Lumbar/Bolster Compressor Motor from the POWER SEAT Fuse through circuit 86 (W/BK or BK/Y) and the Side Support Switch. The motor runs since it is grounded at G400 through circuit 53 (W or BK) and the side support inflates.
