Front Height Will Not Go Up Or Down (Forward & Back Functions Operate Normally)

1) Turn ignition off. Disconnect inoperative power seat switch. Disconnect inoperative power seat motor connector. Using ohmmeter, check resistance between Dark Blue wire harness terminal at seat adjuster connector C1 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 Dark Blue wire. If circuit is okay, replace seat switch.

2) Check resistance between Dark Green wire harness terminal at seat adjuster connector C1 and Black wire harness terminal at seat switch. If resistance is 5 ohms or less, replace front height motor. If resistance is not 5 ohms or less, check for open in Dark Green wire. If circuit is okay, replace seat switch.
