Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdriver set
Wiring diagram (for reference)

2. Inspect Fuses and Circuit Breaker

Locate the fuse box, typically found in the cabin or engine compartment.
Identify the fuse for the power windows based on the vehicle’s owner manual.
Remove the fuse and inspect it for continuity; replace if blown.

3. Test Window Switches

Remove the door panel using a screwdriver and socket set.
Disconnect the window switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed; replace if faulty.

4. Check Wiring and Connections

Inspect the wiring harness for any signs of wear or damage.
Ensure all connectors at the window motor and BCM are secure.
Repair or replace any damaged wires or connectors.

5. Test Power Window Motor

Disconnect the window motor from the window regulator.
Apply direct power from a 12V source to the motor to check for functionality.
If the motor does not operate, replace it.

6. Inspect Window Regulator

Check for any obstructions or damage to the window regulator.
Lubricate moving parts if necessary.
Replace the regulator if it is malfunctioning.
