206CC heater issue

[AndyClockwise]

I have a problem and wondered if anyone can point me in the general direction of the fault.

My girlfriend has a 206CC with a heater that doesn't work.

The LCD display lights up and displays what temperature the heater is set to and also what mode the fan is in but no air hot or cold comes out of the vents.

Is this likely to require a full heater replacement or could it be something simpler?

Thanks, I'll try that on the weekend

I can't hear anything and no air is forthcoming at all
