Replace any faulty components found during testing. Once repairs are made, clear the error codes using the OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved.
How to Access the Window Lockout Circuit
Begin by locating the window lockout switch, usually found on the driver’s door panel. Pressing this switch will activate the lockout function, preventing passengers from using their window controls. Ensure the vehicle is powered on for access.
Next, consult your vehicle’s service manual. It provides specific information about the wiring diagram and location of the window lockout circuit. You’ll typically find this circuit in the door harness or the central body module.
To access the circuit, remove the door panel. Start by unscrewing any visible screws, then use a trim tool to gently pry off the panel, disconnecting any clips as you go. Be cautious of any wiring connections to the window motor or lockout switch.
Once the panel is off, inspect the wiring harness. Look for frayed wires or faulty connections, as these can cause the “B3824 – Window Lockout Circuit Low” error. If you identify any damage, repair or replace the affected components.
Use a multimeter to test the lockout circuit’s voltage and continuity. Verify that the circuit operates correctly by checking for proper voltage at the switch and the window motor. This step confirms whether the issue lies within the circuit or the switch itself.
After testing, reassemble the door panel in reverse order. Ensure all clips and screws are secured, and verify that the window controls operate as intended before finalizing the repair.
Testing the Window Lockout Switch
Begin the testing process by ensuring the vehicle’s ignition is in the OFF position. Disconnect the vehicle battery to avoid any electrical issues during testing.
Step-by-Step Testing Procedure
Follow these steps to check the window lockout switch functionality:
- Locate the window lockout switch on the driver’s door panel.
- Using a multimeter, set it to the continuity or resistance setting.
- With the switch in the OFF position, probe the terminals of the switch. There should be no continuity; this confirms it is not engaging.
- Toggle the switch to the ON position and check again. This time, continuity should exist, indicating the switch is functional.
- If continuity is absent in the ON position, the switch may need replacement.
- Reconnect the battery and test the power windows. The lockout feature should only disable rear window controls from the driver’s position.
Troubleshooting Tips
If the window lockout feature is still malfunctioning, inspect the wiring harness for damage or poor connections. Continuity tests can be performed on the wiring to ensure no breaks exist along the circuit. If all checks pass, consider replacing the switch unit.
| Condition | Action |
|---|---|
| No continuity in OFF position | Switch is functional |
| No continuity in ON position | Replace switch |
| All connections good, windows still inoperable | Inspect wiring harness |
Regular testing ensures your window lockout switch operates correctly, enhancing safety for passengers and preventing accidental operation of windows.
Identifying Wire Issues in the Circuit
Check the wiring harness for damaged or frayed wires. Use a multimeter to measure resistance along the wire to identify breaks or shorts.
