Connect another jumper wire between left rear window switch connector Red/Light Blue and Yellow/Black wire terminals. Turn ignition switch to RUN position. If left rear window operates in UP direction, replace inoperative window switch. Clear DTCs and retest system. If left rear window does not operate in UP direction, remove jumper wires and go to next step.
  8. Turn ignition switch to OFF position. Disconnect left rear power window motor connector. See POWER WINDOW MOTOR  under REMOVAL & INSTALLATION. Measure resistance in Yellow/Black wire between left rear window switch connector and left rear power window motor connector. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Yellow/Black wire. Clear DTCs and retest system.
  9. Measure resistance in Yellow/Light Blue wire between left rear window switch connector and left rear power window motor connector. If resistance is less than 5 ohms, replace left rear power window motor. If resistance is greater than 5 ohms, repair open in Yellow/Light Blue wire. Clear DTCs and retest system.
