Tools Needed:

Parts Needed (if necessary):
- 4 Wheel Drive Switch Assembly
Instructions:
1. Disconnect the battery. This is an important safety precaution to prevent any accidental electrical shocks while working on the switch.
2. Locate the 4 Wheel Drive Switch. The 4 Wheel Drive Switch is located on the dashboard of your Grand Wagoneer, usually to the left of the steering wheel.
3. Remove the switch bezel. The switch bezel is the plastic cover that surrounds the switch. Use a flat head screwdriver to pry it off gently.
4. Remove the switch mounting screws. There are two screws that hold the switch in place. Use a Phillips head screwdriver to remove them.
5. Pull out the switch. Once the screws are removed, you can pull out the switch from the dashboard. Disconnect the electrical connector from the switch. Be careful not to damage the connector or the wires.
6. Inspect the switch. Check for any visible damage to the switch, such as cracks or broken parts. If you find any damage, you will need to replace the switch.
7. Clean the switch contacts. Use a cotton swab dipped in isopropyl alcohol to clean the electrical contacts on the switch. Make sure to dry the contacts thoroughly before reconnecting the switch.
8. Re-solder the switch terminals (optional). If the electrical contacts are damaged or worn, you may need to re-solder them. Use a soldering iron and solder to reconnect the wires to the terminals.
9. Reconnect the switch. Plug the electrical connector back into the switch.
10. Remount the switch. Place the switch back into the dashboard and secure it with the two mounting screws.
11. Replace the switch bezel. Snap the switch bezel back into place.
12. Reconnect the battery. Reconnect the negative battery cable to the battery.
Test the 4 Wheel Drive Switch:
- Start your vehicle.
- Shift into 4 Wheel Drive.
- Verify that the 4 Wheel Drive indicator light on the dashboard illuminates.
- Shift back into 2 Wheel Drive.
- Verify that the 4 Wheel Drive indicator light turns off.
If the 4 Wheel Drive indicator light does not illuminate or does not turn off, there may be a problem with the switch or other components of the 4 Wheel Drive system. You may need to take your vehicle to a qualified mechanic for further diagnosis and repair.
