Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Pull the fuse and check for continuity with a multimeter. Replace if blown.

3. Test and Replace Window Switches

Tools Required: Multimeter, screwdriver.
Remove the door panel using a screwdriver and trim removal tool.
Disconnect the window switch connector and test for continuity with a multimeter.
If the switch fails the test, replace it with a new switch.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness for frays, shorts, or corrosion.
Use electrical contact cleaner to clean corroded connectors.
Repair or replace damaged wiring as necessary.

5. Test and Replace Window Motors (if needed)

Tools Required: Multimeter, screwdriver, direct battery connection cables.
Connect the window motor directly to a battery to check for operation.
If the motor does not operate, remove it from the door and replace it with a new one.
