My heater in the cab has stopped working.

My heater in the cab when driving suddenly stopped working no power so I checked the fuses under the dash on the left and all OK, anyone got any ideas please.

If you are talking about the blower, does it only work on speed 4?

The blower switch can fail, also there is a device to run the lower speeds that can fail, but that normally allows full speed still, even when failed.

Because that is a standard problem: probably a resistor pack near the air inlet.

No its completely dead that's why I expected the fuse to have blown, that's if I'm checking the correct fuses I guess

I removed the relay in the fuse box in the engine bay and just plugged it back in again. It's worked fine ever since
Can't remember which relay it was off hand but it's in the manual.
