Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.

2. Inspect and Test the Window Lock Switch

Locate the window lock switch on the driver’s side door.
Press the switch to toggle it on and off, then attempt to operate the windows again.

3. Check and Replace the Power Window Fuse

Locate the fuse box under the dashboard or hood.
Identify the power window fuse (refer to the owner’s manual for location).
Remove the fuse and inspect it for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage (typically 30A).

4. Test Power at the Window Switch

Reconnect the battery.
Use a multimeter to check for voltage at the power window switch.
If no power is detected, trace the wiring back to the fuse and inspect for breaks.

5. Test the Window Motor

Disconnect the window motor from its connector.
Using jumper wires, connect the motor directly to a 12V battery to see if it operates.
If the motor works, the issue may lie in the switch or wiring.

6. Replace Faulty Components

If the window motor or switch is defective, remove the old component.
Install the new window motor or switch, ensuring all connections are secure.
Reassemble any panels removed during the process.
