Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety before starting any electrical work.

2. Inspect and Replace Fuses

Tools Required: Fuse puller, replacement fuses
Locate the fuse box and identify the power window fuse.
Remove the blown fuse using the fuse puller.
Replace it with a fuse of the same amperage rating.

3. Test and Replace Window Switches

Tools Required: Multimeter, screwdriver
Use the multimeter to test each window switch for continuity.
If a switch is faulty, remove the panel covering the switch.
Disconnect the old switch and install a new switch by connecting the wiring harness.

4. Check and Replace Window Motors

Tools Required: Socket set, torque wrench
Remove the door panel to access the window motor.
Disconnect the motor wiring harness and test the motor with direct power to check functionality.
If the motor is defective, remove it by unscrewing the mounting bolts and install a new motor in reverse order.

5. Inspect and Repair Window Regulators

Tools Required: Socket set, lubricant
With the door panel removed, inspect the window regulator for any physical damage or blockages.
If damaged, replace the regulator by removing the old unit and installing a new one, ensuring all connections are secure.
