The LH and RH power seat system each consist of the seat switch and five reversible motors (front height, rear height, forward/back, recline, and headrest) which operate independently of each other. Each motor contains an electronic circuit breaker (PTC), which will reset only after voltage has been removed from the motor. Battery positive voltage (B+) is supplied at all times to each seat switch via CKT 3740 (ORN) from the rear junction block PWR SEAT circuit breaker. The LH seat switch is supplied ground via CKT 550 (BLK) to G302. The RH seat switch is supplied ground via CKT 650 (BLK) to G302.

When the seat switch is operated to move the entire seat forward, battery positive voltage (B+) is applied via the entire seat forward switch contacts and CKT 285 (TAN) (LH) or CKT 296 (TAN) (RH) to the forward/back motor. The motor is grounded via CKT 284 (LT GRN) (LH) or CKT 290 (LT GRN) (RH) and the entire seat back switch contacts to ground. The motor runs to drive the seat forward until the switch is released. Moving the entire seat back works similarly to moving the entire seat forward except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the entire seat to move back.

When the seat switch is operated to tilt the rear height up, battery positive voltage (B+) is applied via the rear height up switch contacts and CKT 282 (YEL) (LH) or CKT 288 (YEL) (RH) to the rear height motor. The motor is grounded via CKT 283 (LT BLU) (LH) or CKT 289 (LT BLU) (RH) and the rear height down switch contacts to ground. The motor runs to drive the rear of the seat up until the switch is released. Tilting the rear height down works similarly to tilting the rear height up except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the rear of the seat to tilt up.

When the seat switch is operated to tilt the front height up, battery positive voltage (B+) is applied via the front height up switch contacts and CKT 286 (DK GRN) (LH) or CKT 297 (DK GRN) (RH) to the front height motor. The motor is grounded via CKT 287 (DK BLU) (LH) or CKT 298 (DK BLU) (RH) and the front height down switch contacts to ground. The motor runs to drive the front of the seat up until the switch is released. Tilting the front height down works similarly to tilting the front height up except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the front of the seat to tilt up.

When the entire seat switch is pushed to move the entire seat up position, battery positive voltage (B+) is applied via both the front height up and rear height up switch contacts to the front height and rear height motors. The motors are grounded via the front height down and rear height down switches that are not being operated. Both motors run to drive the entire seat up. A similar action occurs to move the entire seat down.

When the seat switch is operated to recline the seat back forward, battery positive voltage (B+) is applied via the recline forward switch contacts and CKT 276 (LT GRN) (LH) or CKT 76 (DK GRN) (RH) to the recline motor. The motor is grounded via CKT 277 (LT BLU) (LH) or CKT 77 (DK BLU) (RH) and the recline back switch contacts to ground. The motor runs to recline the seat back forward until the switch is released. Moving the recline back works similarly to moving the recliner forward except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the back of the seat to move back.

When the seat switch is operated to move the headrest up, battery positive voltage (B+) is applied via the headrest up switch contacts and CKT 1257 (WHT/BLK) (LH) or CKT 1625 (LT GRN) (RH) to the headrest motor. The motor is grounded via CKT 1258 (BLU/WHT) (LH) or CKT 1626 (YEL) (RH) and the headrest down switch contacts to ground. The motor runs to drive the headrest up until the switch is released. Moving the headrest down works similarly to moving the headrest up except that the battery positive voltage (B+) and ground are on the opposite circuits causing the motor to run in the opposite direction driving the headrest up.
