Fuses and Relays:

Fuses: Protect the window circuit from electrical surges. A blown fuse will stop the power window from working altogether.
Relays: Act as switches for the power window motor. A faulty relay can prevent the motor from receiving power, making the window unresponsive.

It’s important to check fuses and relays when troubleshooting power window issues. Have you ever had to replace a fuse o r relay in your Hilux?
