Solution

1. Preparation

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

2. Inspect and Replace Window Switch

Tools Required: Screwdriver, multimeter
Remove the door panel using a screwdriver to access the window switch.
Disconnect the switch connector and test for continuity with a multimeter.
If faulty, replace the window switch with a new one by reconnecting the harness and securing the panel back.

3. Check and Replace Fuses

Tools Required: Fuse puller or pliers
Locate the fuse box; consult the owner's manual for the fuse diagram.
Identify the fuse related to the front windows and check for continuity.
Replace with a new fuse of the same amperage if blown.

4. Inspect Wiring and Connectors

Tools Required: Wire stripper, electrical tape, or soldering kit
Follow the wiring harness from the switch to the window motor.
Look for damaged wires or loose connections.
Repair any damaged wiring using electrical tape or soldering as necessary.

5. Test and Replace Window Motor or Regulator

Tools Required: Socket set, torque wrench
If the window switch and fuses are functional, disconnect the wiring from the window motor.
Using jumper wires, connect the motor directly to the battery to test its operation.
If the motor does not work, replace it. To do so, remove the door panel, unbolt the motor from the regulator, and install a new motor.
If the regulator is faulty, replace it following a similar process.
