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.

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.

Broken most bits now
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.
