Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Check and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box and identify the fuse related to the power windows (refer to the owner’s manual for the specific fuse location).
Remove the fuse and inspect it for continuity; if it is blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the windows again.

3. Inspect and Repair Wiring

Tools Required: Screwdriver set, multimeter
Remove the door panel to access the wiring harness.
Visually inspect all wiring and connectors for damage or corrosion.
Use a multimeter to check for continuity in the wires; repair or replace any damaged wiring.

4. Test and Replace Window Switch

Tools Required: Multimeter, replacement switch (if necessary)
Disconnect the window switch from its harness.
Test the switch with a multimeter to ensure it is sending signals to the window motor.
If the switch is faulty, replace it with a new one and reconnect the wiring.

5. Check Body Control Module (BCM)

If no issues are found with fuses, wiring, or switches, the BCM may need to be reset or replaced.
Tools Required: OBD-II scanner
Use an OBD-II scanner to check for BCM faults and clear any error codes.
If the BCM is faulty, it may require reprogramming or replacement by a qualified technician.
