Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery cable to prevent electrical shock.

2. Inspect and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually found in the glove compartment or under the dashboard).
Remove the cover and find the fuse for the power windows (refer to the owner's manual for specific location).
Inspect the fuse; if it’s blown, replace it with a new fuse of the same amperage (typically 30A).
Reinstall the fuse box cover and reconnect the battery.

3. Test Power Window Switches

Tools Required: Multimeter.
Remove the door panel to access the power window switch.
Disconnect the switch connector and test for continuity using a multimeter.
If the switch is faulty, replace it with a new switch.

4. Check and Replace Window Motor

Tools Required: Socket set, screwdrivers.
With the door panel removed, locate the window motor.
Disconnect the motor connector and apply direct voltage from a power source (12V battery) to the motor terminals.
If the motor does not operate, replace it with a new motor.
Reinstall the door panel after replacing or repairing components.

5. Inspect and Repair Wiring

Tools Required: Wire strippers, electrical tape, soldering iron (if necessary).
Visually inspect the wiring harness for any signs of wear, fraying, or corrosion.
Repair any damaged wires by splicing in new wire or using electrical tape.
Ensure all connections are secure and properly insulated.
