If it's a classic did you check both fuse boxes ? , cos it sounds like either a fuse or earth fault

If it's not broke .....upgrade it 😊

Which fuses did you check ?under the dash or main box in engine bay?

Haha must have posted at same time Clive!

I had the same thing with rear lights, it turned out to be a fuse but obviously not helping much, I'll rack my brains.

Thanks stants I've even disconnected the entire fuse box to clean the terminals they wer a little corroded but not that bad really so cleaned them and reconnected still nothing the heaters still blow hot air and can change to cold and were it comes from just no control of the power of it

I'm not too hot on sparky stuff tbh but the loom runs under the rad at the front of the car and if it's not "clipped" to the lower valance it can melt on the headers . So maybe check that area of the loom is ok and the earth's are making a good contact?

If it's not broke .....upgrade it 😊

My heater doesn't work on the low powers, only on full, saw somewhere there is a resistor in the wiring that controls that. Managed to get the fan spinning on low though if I jiggle the wires connecting to the fan :)
