Solution

1. Preparation

Gather necessary tools: Socket set, multimeter, screwdrivers, and a trim removal tool.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect and Replace the Fuse

Locate the fuse box: Refer to the owner’s manual for the exact location.
Remove the fuse related to the power windows using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace with a new fuse of the same amperage.

3. Check and Repair Wiring

Remove the door panel using the trim removal tool to access the wiring harness.
Visually inspect all wiring for fraying, cuts, or disconnections.
If damaged, repair the wiring by splicing in new wiring or connectors as needed.

4. Test and Replace Window Motor

With the door panel removed, locate the window motor.
Use a multimeter to check for voltage at the motor connector while activating the switch.
If no power is detected, the issue may lie with the switch or relay; if power is present, replace the window motor.
- Remove the window motor by unscrewing the mounting bolts and disconnecting the wiring harness.
- Install the new motor by reversing the removal steps and ensure it is securely mounted.

5. Reassemble and Test

Reattach the door panel carefully, ensuring no clips are left behind.
Reconnect the negative terminal of the battery.
Test all power windows for proper operation.
