Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or pliers.
Locate the fuse box (often under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse diagram.
Pull the fuse and inspect it for continuity. Replace if blown with the same amperage fuse.

3. Test and Replace Window Switches

Tools Required: Multimeter, flathead screwdriver.
Remove the door panel to access the window switch assembly.
Use a multimeter to check for continuity across the switch contacts when pressed.
If there is no continuity, replace the switch with a new one by disconnecting the wiring harness and installing the new switch.

4. Inspect Wiring Harness

Tools Required: Wire strippers, electrical tape.
Check the wiring harness leading to the door for any signs of wear, fraying, or disconnections.
Repair any damaged wires by splicing with new wire and securing with electrical tape.
Ensure all connectors are properly seated.

5. Test Window Motor Operation

Tools Required: Multimeter, jumper wires.
Connect jumper wires to the window motor terminals to provide direct power.
If the motor operates, the issue may lie in the switch or wiring. If not, the motor may need replacement.
