Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse panel, typically under the dashboard or in the engine compartment.
Remove the power window fuse using the fuse puller.
Inspect the fuse visually or use a multimeter to check continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Test and Replace Power Window Switch

Tools Required: Multimeter, flathead screwdriver
Remove the cover of the power window switch using the flathead screwdriver.
Disconnect the switch connector.
Test the switch for continuity with a multimeter; if it fails, replace the switch with a new one.
Reconnect the new switch and test its operation.

4. Inspect Wiring and Connectors

Tools Required: Wire strippers, electrical tape
Visually inspect the wiring harness leading to the window motors for frays or breaks.
If damage is found, repair using wire strippers to cleanly splice and tape the wires securely.
Ensure all connectors are seated properly and free of corrosion.

5. Test Window Motor

Tools Required: Jumper wires
Disconnect the window motor from the harness.
Use jumper wires to connect the motor directly to the battery to check for operation.
If the motor does not operate, it may need to be replaced.

6. Reassemble

Once repairs are made, reconnect all components and covers.
Reconnect the vehicle battery and test all windows to ensure they function correctly.
