Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire connectors, and a replacement fuse if needed.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover.
Use the multimeter to check for continuity in the fuse; if it’s blown, replace it with a fuse of the same amperage (usually 15A or 30A depending on model).

3. Inspect and Replace Window Switch

Remove the door panel using a screwdriver to access the window switch assembly.
Disconnect the electrical connector from the window switch.
Test the switch for continuity using a multimeter; replace it if defective.
Reconnect the new switch and reassemble the door panel.

4. Test the Window Motor

If the switch is functioning, apply direct power to the window motor using jumper wires and a battery (ensure correct polarity).
If the motor operates, clean the connector and reassemble; if it does not, proceed to replace the window motor.

5. Replace Window Motor (if necessary)

Remove the door panel again to access the window motor.
Disconnect the motor connector and remove mounting screws.
Install the new window motor, ensuring it is securely mounted.
Reconnect the electrical connector and reassemble the door panel.
