Entire Seat Will Not Go Forward Or Back (Up & Down Functions Operate Normally)
1) Turn ignition off. Disconnect inoperative power seat switch. Disconnect inoperative power seat motor connector. Using ohmmeter, check resistance between Light Green wire harness terminal at seat adjuster connector C2 and Black wire harness terminal at seat switch. If resistance is 5 ohms or less, go to next step. If resistance is not 5 ohms or less, check for open in Light Green wire. If circuit is okay, replace seat switch.
2) Check resistance between Tan wire harness terminal at seat adjuster connector C2 and Black wire harness terminal at seat switch. If resistance is 5 ohms or less, replace forward/back motor. If resistance is not 5 ohms or less, check for open in Tan wire. If circuit is okay, replace seat switch.
