1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, Phillips screwdriver.
Disconnect the negative terminal of the battery to ensure safety while working on the electrical system.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the fuse related to the power windows using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Replace Window Switch (if necessary)

Remove the door panel using a Phillips screwdriver and flathead screwdriver to access the window switch.
Disconnect the wiring harness from the window switch and replace with a new switch.
Reattach the door panel securely.

4. Test or Replace Window Motor/Regulator (if necessary)

If the switch is functioning properly, remove the door panel again to access the window motor.
Disconnect the motor's wiring harness and use a multimeter to check for voltage when the switch is activated.
If voltage is present but the motor does not operate, remove the motor and replace it with a new one.
If the regulator is faulty, replace it following the manufacturer’s instructions, ensuring it is properly aligned.
