Hi can anybody help , My heater has stopped working , the climate control panel still displays as normal , but no heat or fan speed control , any info greatly appreciated

When you press the defrost (windscreen symbol) button, does the heater work then?

I had one of these do a similar thing last year; the disply displayed everything, but the heater would only work if you pressed defrost. I needed a new climate control panel; £175 from a breaker.

hi , no nothing at all ,display remains all good but no function from any of the keys , would it be a safe bet to say its the control panel and not the blower fan itself?

IIRC on the car I had some of the keys would work, but I could not increase the temperature or alter the direction of the fan unless defrost was pressed. Basically what had happened was the contacts behind the 'heat' symbol had worn out over time - you might feel no 'click' when you press heat, but will feel it 'click' when you press cold if this is the case.
