Any Power Window Inoperative

  1. Remove driver's power window master switch with connector attached. Measure voltage by backprobing between master switch terminal No. 6 and ground. See Figure. With master window lock switch in LOCK position, voltage should be zero volts. With master window lock switch in NEUTRAL position, voltage should be 10-14 volts. If voltage is as specified, go to next step. If voltage is not as specified, replace master power window switch.
  2. Remove power window control switch where window operation is faulty and remove connector from control switch. Place master window lock switch in NEUTRAL position. Turn ignition switch to ON position. Measure voltage between appropriate power window control switch harness connector terminal No. 11 and ground. See Figure. Voltage should be 10-14 volts. If voltage is as specified, go to next step. If voltage is not as specified, repair open in Yellow/Black wire between master power window control switch terminal No. 6 and appropriate power window control switch terminal No. 11. See WIRING DIAGRAMS .
  3. Measure voltage between appropriate power window control switch harness connector terminal No. 7 and ground. See Figure. Voltage should be 10-14 volts. If voltage is as specified, go to next step. If voltage is not as specified, repair open in Red wire between POWER fuse and affected power window control switch terminal No. 7. See WIRING DIAGRAMS .
  4. Turn ignition switch to OFF position. Check for continuity between appropriate power window control switch harness connector terminal No. 12 (White/Black wire) and ground. See Figure. If continuity is present, go to next step. If continuity is not present, repair open in White/Black wire between affected power window control switch terminal No. 12 and ground. See WIRING DIAGRAMS .
  5. Connect jumper wire from 12-volt battery positive terminal to appropriate power window control switch harness connector terminal No. 6. See Figure. Connect another jumper wire from battery negative terminal to power window control switch harness connector terminal No. 1. Window glass should raise. Reverse polarity on jumper wires and window glass should lower. If power window motor does not operate as specified, go to next step. If power window motor operates as specified, fault may be intermittent. Check all connectors and terminals for poor connection and retest. See WIRING DIAGRAMS .
  6. Check power window motor operation. See appropriate POWER WINDOW MOTOR TEST  under COMPONENT TESTS. If power window motor operates correctly, go to next step. If power window motor does not operate correctly, replace power window motor.
  7. Check for continuity in Yellow wire between power window control switch harness connector terminal No. 1 and power window motor harness connector terminal No. 4. See Figure and Figure . Check for continuity in Green wire between power window control switch harness connector terminal No. 6 and power window motor harness connector terminal No. 1. If continuity is present at both measurements, fault may be intermittent. Check all connectors and terminals for poor connection and retest. If continuity is not present, repair open in appropriate wire and retest. See WIRING DIAGRAMS .
