Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or pliers
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the fuse associated with the power windows (refer to the owner's manual for the exact location).
Remove the fuse and inspect it visually for signs of damage or a blown filament.
If blown, replace it with a new fuse of the same amperage.

3. Test Power Window Switches

Tools Required: Multimeter
Remove the switch panel using a trim tool or screwdriver.
Disconnect the wiring harness from the switch.
Set the multimeter to continuity mode and test the switch terminals when pressed.
If no continuity is detected, replace the power window switch.

4. Inspect and Repair Wiring

Tools Required: Multimeter, electrical tape, wire connectors
Inspect the wiring harness for any visible damage, fraying, or disconnections.
If any wires are damaged, splice them and use electrical tape or connectors to secure the repair.
Ensure all connections are tight and secure before reassembling.

5. Test the Window Motors

Tools Required: Multimeter, jumper wires
Connect jumper wires directly to the power window motor terminals to test functionality.
If the motor works with direct power, the issue is likely with the switch or wiring.
If the motor does not work, replace the window motor.
