Solution

1. Preparation

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

2. Check and Replace Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box and remove the cover.
Identify the power window fuse using the diagram on the fuse box cover.
Pull the fuse out and inspect for continuity. Replace it if blown with a fuse of the same amperage.

3. Inspect Power Window Switch

Tools Required: Multimeter
Remove the door panel to access the window switch.
Disconnect the electrical connector from the switch.
Using a multimeter, test for continuity across the switch terminals when pressed. If not functioning, replace the switch.

4. Check Wiring and Connections

Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
If damage is found, repair or replace the wiring as necessary to ensure a good connection.

5. Test Window Motor

Tools Required: Jumper wires
Disconnect the window motor from the regulator.
Use jumper wires to connect the motor directly to a power source (battery). If the motor operates, it is functioning correctly; if not, replace the motor.

6. Examine Window Regulator

Inspect the window regulator mechanism for any obstructions or damage.
If the regulator is jammed or broken, replace it according to the manufacturer’s specifications.
