Solution

1. Preparation

Gather tools: socket set, flathead screwdriver, Phillips screwdriver, multimeter, and wire stripper.
Disconnect the vehicle's battery to prevent electrical shock.

2. Check and Replace Fuses

Locate the Fuse Box: Find the fuse box under the dashboard or in the engine compartment.
Remove the Fuse: Use a fuse puller or pliers to gently remove the power window fuse.
Inspect the Fuse: Check if the fuse is blown (the metal strip inside will be broken).
Replace if Necessary: If blown, replace it with a fuse of the same amperage.

3. Remove Door Panel

Unscrew Fasteners: Use a screwdriver to remove screws securing the door panel.
Pry Off the Panel: Carefully use a flathead screwdriver to pry off the door panel clips.
Disconnect Wiring: Unplug any wiring harnesses connected to the door panel.

4. Test and Replace Window Switch

Check for Continuity: Use a multimeter to test the window switch for continuity.
Replace Switch: If defective, disconnect the old switch and install a new one by reversing the removal process.

5. Inspect and Replace Window Motor/Regulator

Test Motor: Apply direct power to the motor using jumper wires to see if it operates.
Remove Motor/Regulator: If it doesn’t work, remove the window motor and regulator by unscrewing the mounting bolts.
Install New Component: Replace with a new window motor or regulator as necessary, ensuring all connections are secure.

6. Reassemble Door Panel

Reconnect Wiring: Plug in any disconnected wiring harnesses.
Reattach Panel: Align the panel back onto the door and press it firmly to snap it into place.
Reinsert Screws: Screw back any screws removed earlier.
