All power windows stopped working in Suzuki Swift – fuse o r switch issue?

Yesterday, all four power windows in my 2021 Suzuki Swift suddenly stopped working at the same time. None of the switches respond, even from the driver-side master control. Could this be a blown fuse, relay issue, o r something related to the cars electrical system? Has anyone in Pakistan experienced this before with their Swift?

When all four power windows stop working in a Suzuki Swift at once, its almost always an electrical issue rather than a mechanical one. Here’s how to diagnose and fix it:

Likely Causes:
Blown Fuse:
The most common reason is a blown fuse. The power windows are typically on a shared fuse. Check the fuse box usually under the dashboard o r in the engine bay and replace the window-related fuse if it’s blown.

Faulty Window Relay:
Power windows operate using a relay, which can fail over time. If the fuse is okay, the relay may need replacement.

Driver-Side Master Switch Fault:
If the main control switch on the driver’s side is faulty, it can cause all windows to stop functioning. This is a known issue with some Swift models.

Battery o r Wiring Issue:
A sudden voltage o r loose wiring especially after rain o r roadside repairs can cut power to the window system.

Solutions:
Inspect and replace the power window fuse if needed.

Check the window relay a mechanic o r electrician can help test this.

Test the master window switch unit replacing it can fix the problem.

Inspect for loose wiring o r signs of corrosion, especially near the fuse box.

Note: If the problem occurred after rain, check for water ingress near the door panel o r under the dashboard.
