Test D: Right Front Power Window Is Inoperative

NOTE: Ensure lock-out switch is in OFF position before testing.
NOTE: Left front door power window switch is located on door trim panel and all windows can be controlled from this switch. Switch is referred as master power window switch.
NOTE: Perform all voltage and resistance tests using a Digital Volt-Ohm Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
  1. Turn ignition switch to RUN position. Operate right front power window from master power window switch. If right front power window does not operate, go to next step. If right front power window operates, go to step  16.
