Locate the fuse box, typically found under the driver's side dashboard or in the engine compartment.
Identify the fuse for the power windows using the fuse diagram.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it’s blown, replace it with a fuse of the same amperage.
Reconnect the battery and test the window operation.

Test the switch with a multimeter for continuity.
If defective, replace the switch with a new one.
Reconnect the switch and reassemble the door panel.

4. Test and Replace the Window Motor

If the switch is functional, proceed to test the window motor.
Disconnect the wiring harness from the window motor.
Apply direct power from the battery to the motor using jumper wires.
If the motor does not operate, it should be replaced.
Remove the old motor and install the new motor, following manufacturer specifications.
