Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

Tools Required:

OBD-II scanner
Multimeter
Screwdriver set
Socket set
Wire strippers/crimpers

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Check if the fuse is blown (the metal strip inside will be broken).
If blown, replace it with a new fuse of the same amperage.

3. Test and Replace Window Switches

Remove the door panel using a screwdriver and socket set to access the window switch assembly.
Disconnect the wiring harness from the switch.
Use a multimeter to test for continuity across the switch terminals when activated.
If no continuity is found, replace the switch with a new one.

4. Inspect Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or disconnections.
Repair any damaged wires using wire strippers and crimpers.
Ensure all connectors are securely fastened.

5. Test Window Motor

If the switches and wiring seem functional, access the window motor.
Disconnect the motor from the window regulator.
Use jumper wires to connect the motor directly to the battery to test its operation.
If the motor does not operate, replace it with a new unit.

6. Reassemble

Reinstall the door panel and secure it with screws.
Reconnect the negative battery terminal.
Test all power windows for proper operation.
