All power windows in my Suzuki Swift stopped working at once – what could be wrong?

Today, all four power windows of my 2021 Suzuki Swift suddenly stopped working. No sound o r movement at all. The central lock works fine. Could this be a blown fuse, bad relay, o r master switch issue? Where should I start checking?

When all power windows fail simultaneously, the issue is likely centralized in the electrical system.

Most Common Causes:
Blown fuse o r bad relay: The power windows usually share a fuse o r relay.

Driver-side master switch failure: If the control unit fails, none of the windows will operate.

Loose o r broken wiring connection—especially after any recent repair o r modification.

What to Check:
Locate the fuse box under the dashboard o r hood and check the window fuse.

If the fuse is intact, have an electrician test the relay and switch unit.

Inspect the master switch with a multimeter to check continuity.
