Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace the Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box, typically found under the dashboard or in the engine bay.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it for continuity; replace it if blown.

3. Repair or Replace Window Switch

Tools Required: Screwdriver set, multimeter.
Remove the door panel or trim covering the window switch using the appropriate screwdriver.
Disconnect the switch harness and test for continuity with a multimeter.
If defective, replace the switch with a new one and reconnect the wiring.

4. Test and Replace Window Motor or Regulator

Tools Required: Socket set, torque wrench.
Remove the door panel to access the window motor and regulator assembly.
Disconnect the motor from the wiring harness and test it by applying direct power.
If the motor is non-functional, remove it by unscrewing the mounting bolts and replace it with a new motor.
If the regulator is damaged, remove it carefully and install a new regulator, ensuring all bolts are torqued to manufacturer's specifications.
