Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Remove the Door Panel

Remove any screws securing the door panel (typically located near the handle and at the bottom of the panel).
Carefully pry off the door panel using a trim removal tool to avoid damaging clips.
Disconnect any wiring harnesses connected to the door panel (e.g., speakers, window switch).

3. Inspect and Replace the Window Switch

Locate the window switch on the door panel.
Disconnect the wiring harness from the switch.
Use the multimeter to test the switch for continuity; replace if found faulty.
Install the new window switch by connecting the wiring harness and securing it in place.

4. Inspect and Test the Window Motor (if necessary)

If the window switch is functional, check the window motor.
Disconnect the motor's wiring harness and apply direct power using jumper wires to test functionality.
If the motor does not operate, replace it with a new one.

5. Reassemble the Door Panel

Reconnect all wiring harnesses to the door panel.
Align the door panel with the clips and press it into place.
Secure the door panel with screws previously removed.

6. Final Checks

Reconnect the battery and test the window functionality.
Clear any error codes using the OBD-II scanner and check for the return of the B1043 code.
