Why is Rear window demister not working on matiz?

1) Blown fuse: The rear window demister is protected by a fuse, which may have blown. Check the fuse box (usually located under the dashboard or in the engine compartment) and replace the blown fuse.

2) Faulty switch: The switch that turns on the rear window demister may be faulty. Try wiggling the switch or applying some contact cleaner to see if this restores functionality.

3) Broken wire: The wire that supplies power to the rear window demister may be broken or damaged. Check the wiring for any breaks or damage and repair as necessary.

4) Faulty relay: The rear window demister may be controlled by a relay, which may have failed. Check the relay (usually located in the fuse box) and replace it if necessary.

5) Faulty defroster grid: The defroster grid on the rear window may be damaged or have a poor electrical connection. Check the grid for any breaks or damage and repair as necessary.
