Solution

1. Preparation

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

Tools Required:

OBD-II scanner
Multimeter
Socket set
Screwdrivers (flathead and Phillips)
Wire strippers and connectors (if needed)

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the power windows using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any breakage or discoloration.
Replace with a new fuse of the same amperage if necessary.

3. Test the Window Switch

Remove the panel covering the power window switch using a flathead screwdriver.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity across the contacts when the switch is pressed.
If there is no continuity, replace the switch with a new one.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness leading to the power window motor for fraying or damage.
Ensure all connectors are securely attached and free from corrosion.
Repair any damaged wires using wire strippers and connectors.

5. Check the Window Motor

Remove the door panel to access the window motor.
Disconnect the wiring harness from the motor.
Use a multimeter to test for voltage at the motor connector when the switch is pressed.
If voltage is present but the motor does not operate, replace the window motor.
