Disconnect driver's seat control switch 8-pin connector. See SEAT CONTROL SWITCH  under REMOVAL & INSTALLATION. Measure voltage between Dark Green wire terminal at driver's seat control switch connector and ground. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open in Dark Green wire.
  2. Measure resistance between Black wire terminal at driver's seat control switch connector and ground. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open in Black wire.
