Disconnect the negative battery terminal before working on electrical components to prevent short circuits.

2. Check and Replace Fuses

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the fuse for the power windows.
Inspect the fuse; if it's blown, replace it with a fuse of the same amperage (refer to the owner's manual for specifications).

3. Inspect and Replace Window Switch

Remove the door panel using a trim removal tool to access the window switch.
Disconnect the electrical connector from the window switch.
Use a multimeter to test the switch for continuity.
If defective, replace the window switch with a new one, ensuring proper connection.

4. Test and Replace Window Motor

Remove the door panel to access the window motor.
Disconnect the window motor wiring harness.
Using a multimeter, check for voltage at the motor connector while activating the switch.
If voltage is present but the motor doesn't function, replace the window motor.
