SYMPTOM DIRECTORY

Note. On MX-6, disregard information regarding rear windows.

Note. "Main switch/passenger's" refers to passenger's window switch located on main switch. "Main switch/left rear" refers to left rear window switch located on main switch. "Main switch/right rear" refers to right rear window switch located on main switch.

SYMPTOM NO. 1

  1. Turn ignition on. Check 30-amp power window fuse in fuse block, near left kick panel. If fuse is blown, replace fuse (repair wiring if necessary). If fuse is okay, go to next step.
  2. Measure voltage at Black/Red wire terminal of main switch connector. If battery voltage is present, go to next step. If battery voltage is not present, repair Black/Red wire between fuse and main switch.
  3. Disconnect main switch connector. Check continuity between ground and Black wire terminal of main switch connector. If continuity exists, reconnect main switch connector and go to next step. If continuity does not exist, repair Black wire between ground and main switch.
  4. Measure voltage at the following wire terminals of main switch connector with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check main switch. See MAIN SWITCH TEST under COMPONENT TESTING. Green/Blue wire (driver's switch in UP position) Red/Blue wire (driver's switch in DOWN position) Green/White wire (main switch/passenger's in UP position) White/Yellow wire (main switch/passenger's in DOWN position) Blue/White wire (main switch/left rear in UP position) Yellow/White wire (main switch/left rear in DOWN position) Green/Yellow wire (main switch/right rear in UP position) White/Red wire (main switch/right rear in DOWN position).
  5. Measure voltage at the following wire terminals of sub-switch connectors with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, repair wiring between main switch and sub-switch. Green/White wire (main switch/passenger's in UP position) White/Yellow wire (main switch/passenger's in DOWN position) Blue/White wire (main switch/left rear in UP position) Yellow/White wire (main switch/left rear in DOWN position) Green/Yellow wire (main switch/right rear in UP position) White/Red wire (main switch/right rear in DOWN position).
  6. Measure voltage at the following wire terminals of sub-switch connectors with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check sub-switch. See SUB-SWITCH TEST under COMPONENT TESTING. Red wire (main switch/passenger's in UP position) Green wire (main switch/passenger's in DOWN position) Red wire (main switch/left rear in UP position) Blue wire (main switch/left rear in DOWN position) White wire (main switch/right rear in UP position) Yellow wire (main switch/right rear in DOWN position).
  7. Measure voltage at the following wire terminals of window motor connectors with main switches in specified position. If battery voltage is present at all terminals, check window motor. See WINDOW MOTOR TEST under COMPONENT TESTING. If battery voltage is not present at all terminals, repair wiring between main switch and window motor (driver's window), or between sub-switch and window motor (except driver's window). Green/Blue wire (driver's switch in UP position) Red/Blue wire (driver's switch in DOWN position) Red wire (main switch/passenger's in UP position) Green wire (main switch/passenger's in DOWN position) Red wire (main switch/left rear in UP position) Blue wire (main switch/left rear in DOWN position) White wire (main switch/right rear in UP position) Yellow wire (main switch/right rear in DOWN position).

SYMPTOM NO. 2

  1. Turn ignition on. Measure voltage at Green/Blue wire terminal of main switch connector with driver's switch in UP position. Also measure voltage at Red/Blue wire terminal of main switch connector with driver's switch in DOWN position. If battery voltage is present at both terminals, go to next step. If battery voltage is not present at both terminals, check main switch. See MAIN SWITCH TEST under COMPONENT TESTING.
  2. Measure voltage at Green/Blue wire terminal of driver's window motor connector with driver's switch in UP position. Also measure voltage at Red/Blue wire terminal of driver's window motor connector with driver's switch in DOWN position. If battery voltage is present at both terminals, check window motor. See WINDOW MOTOR TEST under COMPONENT TESTING. If battery voltage is not present at both terminals, repair wiring between main switch and window motor.

SYMPTOM NO. 3

  1. Turn ignition on. Measure voltage at the following wire terminals of main switch connector with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check main switch. See MAIN SWITCH TEST under COMPONENT TESTING. Green/White wire (main switch/passenger's in UP position) White/Yellow wire (main switch/passenger's in DOWN position) Blue/White wire (main switch/left rear in UP position) Yellow/White wire (main switch/left rear in DOWN position) Green/Yellow wire (main switch/right rear in UP position) White/Red wire (main switch/right rear in DOWN position).
  2. Measure voltage at wire terminals of sub-switch connectors as specified in previous step with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, repair wiring between main switch and sub-switch.
  3. Measure voltage at the following wire terminals of sub-switch connectors with main switches in specified position. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, check sub-switch. See SUB-SWITCH TEST under COMPONENT TESTING. Red wire (main switch/passenger's in UP position) Green wire (main switch/passenger's in DOWN position) Red wire (main switch/left rear in UP position) Blue wire (main switch/left rear in DOWN position) White wire (main switch/right rear in UP position) Yellow wire (main switch/right rear in DOWN position).
  4. Measure voltage at wire terminals of window motor connectors as specified in previous step with main switches in specified position. If battery voltage is present at all terminals, check window motor. See WINDOW MOTOR TEST under COMPONENT TESTING. If battery voltage is not present at all terminals, repair wiring between sub-switch and window motor.

SYMPTOM NO. 4

Check power cut switch. See POWER CUT SWITCH TEST under COMPONENT TESTING.

SYMPTOM NO. 5

Turn ignition on. Measure voltage at Black/Red wire terminal of each sub-switch connector. If battery voltage is present, check sub-switch. See SUB-SWITCH TEST under COMPONENT TESTING. If battery voltage is not present, repair wiring between fuse and sub-switch.

SYMPTOM NO. 6

Check power cut switch. See POWER CUT SWITCH TEST under COMPONENT TESTING.

SYMPTOM NO. 7

Check main switch. See MAIN SWITCH TEST under COMPONENT TESTING.
