Power Windows Mazda 929 HD

DESCRIPTION & OPERATION

Main switch (master switch) on driver's door controls all windows. Sub-switch on passenger's door and rear doors controls individual window. 929 uses a power cut (window lock-out) switch on driver's door to prevent operation of windows. When power cut switch is in ON position, windows can be operated by main switch or sub-switch. When power cut switch is in OFF position

1. Driver's window can be operated using main switch; no other windows can be operated using main switch or sub-switch.

On vehicles with "one-touch" function, driver's window opens fully when switch button is quickly pressed and released. If switch button is pressed and held, window will go down until button is released. On all other models, one-touch module is part of main switch.

MAIN SWITCH

Check continuity across specified terminals of main switch connector with main switch button held in specified position. See MAIN SWITCH CONTINUITY TEST. (Scheme 1)and (Scheme 2). Replace main switch if continuity is not as specified.

WINDOW MOTOR

Disconnect window motor connector. Apply battery voltage and ground across window motor connector terminals. Reverse polarity to move window in opposite direction. Replace window motor if it does not operate.

TROUBLESHOOTING

SYMPTOM DIRECTORY

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, measure voltage at Red/Blue wire terminal of main switch connector. If battery voltage is not present, repair Red/Blue wire between fuse and main switch.
2. If battery voltage is present, 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.
3. 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»(/mazda/929/hd-1993-1995/remont/windows/#power-windows__main-switch) under COMPONENT TESTING. Red/Black wire (driver's switch in UP position) Green/Black wire (driver's switch in DOWN position) Red/White wire (main switch/passenger's in UP position) Green/Red wire (main switch/passenger's in DOWN position) Red/Yellow wire (main switch/left rear in UP position) Green/Yellow wire (main switch/left rear in DOWN position) Red/Green wire (main switch/right rear in UP position) Light Green/Red wire (main switch/right rear in DOWN position).
4. 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. Red/White wire (main switch/passenger's in UP position) Green/Red wire (main switch/passenger's in DOWN position) Red/Green wire (main switch/left rear or main switch/right rear in UP position) Light Green/Red wire (main switch/left rear or 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, check sub-switch. See «SUB-SWITCH TEST»(/mazda/929/hd-1993-1995/remont/windows/#power-windows__sub-switch) under COMPONENT TESTING. Red wire (main switch/passenger, main switch/left rear or main switch/right rear in UP position) Green wire (main switch/passenger, main switch/left rear or main switch/right rear in DOWN position).
6. 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»(/mazda/929/hd-1993-1995/remont/windows/#power-windows__window-motor) 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). Red/Black wire (driver's switch in UP position) Green/Black wire (driver's switch in DOWN position) Red wire (main switch/passenger, main switch/left rear or main switch/right rear in UP position) Green wire (main switch/passenger, main switch/left rear or main switch/right rear in DOWN position).

SYMPTOM NO. 2

1. Turn ignition on. Measure voltage at Red/Black wire terminal of main switch connector with driver's switch in UP position. Also measure voltage at Green/Black 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»(/mazda/929/hd-1993-1995/remont/windows/#power-windows__main-switch) under COMPONENT TESTING.
2. Measure voltage at Red/Black wire terminal of driver's window motor connector with driver's switch in UP position. Also measure voltage at Green/Black wire terminal of driver's window motor connector with driver's switch in DOWN position.
3. If battery voltage is present at both terminals, check window motor. See «WINDOW MOTOR TEST»(/mazda/929/hd-1993-1995/remont/windows/#power-windows__window-motor) under COMPONENT TESTING. If battery voltage is not present at both terminals, repair wiring between main switch and window motor.
