Note. For door lock control relay and integration relay testing, see DOOR LOCKS - POWER article. For ignition switch testing, see STEERING COLUMN SWITCHES article.
POWER MAIN RELAY
Note. Vehicles use a door lock control relay and a power main relay. For door lock control relay and integration relay testing information, see DOOR LOCKS - POWER article.
- Remove power main relay, located in junction block No. 1 at left side of instrument panel.
- Using an ohmmeter, check continuity between power main relay terminals No. 1 and 2. Continuity should exist. (Scheme 5) Apply battery voltage to terminal No. 1 and ground terminal No. 2. Continuity should exist at terminals No. 3 and 5. If relay does not test as specified, replace power main relay.
Scheme 5
Front Doors
Using a 12-volt battery, connect positive battery lead to either power window motor terminal. Connect negative battery lead to other power window motor connector terminal. Motor should operate. Reverse battery leads. Motor should operate in opposite direction. If motor does not test as specified, replace motor.
5-Door
- Disconnect connector from driver's side power window switch. Connect positive lead of ammeter to driver's side power window switch connector (harness side) terminal No. 6. see scheme 1
- Connect ammeter negative lead to negative terminal of 12-volt battery. Connect jumper wire from positive battery terminal to driver's side power window switch connector (harness side) terminal No. 13.
- While lowering driver's side window, current should be about 7 amps. When window operation is stopped, current should increase to about 14.5 amps or more. If current is as specified, replace driver's side power window switch. If current is not as specified, check and repair appropriate circuit.
3-Door
- Disconnect connector from driver's side power window switch. Connect positive lead of ammeter to driver's side power window switch connector (harness side) terminal No. 3. see scheme 2
- Connect ammeter negative lead to negative terminal of 12-volt battery. Connect jumper wire from positive battery terminal to driver's side power window switch connector (harness side) terminal No. 4.
- While lowering driver's side window, current should be about 7 amps. When window operation is stopped, current should increase to about 14.5 amps or more. If current is as specified, replace driver's side power window switch. If current is not as specified, check and repair appropriate circuit.
