Solution

1. Preparation

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

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse for the power windows using the diagram on the fuse box cover.
Remove the fuse and check if it is blown; replace it with a fuse of the same amperage if necessary.

3. Access the Window Switch

Remove the door panel using a trim tool and screwdriver to access the window switch.
Disconnect the electrical connector from the switch and inspect for damage.
If the switch is faulty, replace it with a new one.

4. Test and Replace the Power Window Motor

If the switch is functioning, use a multimeter to check for voltage at the motor connector while operating the switch.
If there is no voltage, trace the wiring back to the switch and check for continuity.
If voltage is present but the motor does not respond, remove the motor by unscrewing it from the regulator.
Replace with a new power window motor if it has failed.

5. Inspect and Repair Wiring

Examine the wiring harness for any frays, cuts, or corrosion.
Repair any damaged wires with appropriate connectors and electrical tape.
Ensure connections are tight and secure.

6. Reassemble Door Panel

Reattach the door panel by aligning it properly and securing all clips and screws.
Reconnect the battery and test the power windows for proper operation.
