Disconnect the negative battery terminal to prevent electrical shorts.

Tools Required:

Multimeter
Screwdriver set
Pliers
Wiring harness repair kit (if necessary)

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse using the fuse diagram.
Remove the fuse and inspect it for continuity. Replace if blown.

3. Test and Replace the Window Switch

Remove the door panel using a screwdriver and pliers to access the power window switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity across the switch terminals.
Replace the switch if it shows no continuity.

4. Inspect Wiring and Connections

Examine the wiring harness for any signs of wear, fraying, or breaks.
Repair any damaged wires using a wiring harness repair kit.
Ensure all connectors are securely attached and free of corrosion.

5. Test the Window Motor

Disconnect the power window motor from the door.
Use a multimeter to check for voltage at the motor connector while operating the switch.
If there is voltage but no motor operation, replace the window motor.
