Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, fuse puller, wire strippers, electrical tape.
Disconnect the vehicle battery to ensure safety before working on electrical components.

2. Inspect and Clean Switches

Remove the switch panel using a flathead screwdriver or prying tool.
Disconnect the wiring harness from the switch.
Clean any debris from the switch contacts with electrical cleaner.
Reconnect the switch and test operation.

3. Check and Replace Fuses

Locate the fuse box; refer to the owner’s manual for the specific fuse related to the power windows.
Pull the fuse and inspect it for continuity using a multimeter.
If blown, replace with the same amperage fuse (typically 15A or 20A depending on the circuit).
Reinstall the fuse and test window operation.

4. Inspect Wiring Harness

Visually inspect the wiring harness leading to the window motor for any visible damage or wear.
If damage is found, repair or replace the affected wires using wire strippers and electrical tape.

5. Test and Replace Window Motor

Disconnect the window motor from the wiring harness.
Use a multimeter to check for voltage at the connector when the switch is activated.
If voltage is present but the motor does not operate, replace the window motor.
To replace, remove the door panel, unbolt the motor, and disconnect the wiring. Install the new motor and reverse the steps.

6. Reassemble Components

Reattach the door panel securely, ensuring all clips and screws are in place.
Reconnect the vehicle battery.
