The fan works on all speeds but there is no heat coming through wether the temperature dial is on hot or cold, both sides of the matrix hoses seem to be ok so is this a simple fix with a new heater unit or what? help would be appreciated.. cheers dan

It could be the electric motor that operates the heater flap. Have a look here:

It could also be the temp sensor in the contol dial. You know how it has 2 small vents between the dials at the bottom (either side of the recirc button) blow hard in these vents there maybe dirt on the temp sensor - or it could be faulty.

I have replace my motor and my whole control unit, my heating now works!

cheers guys ill try this tonight !

Might sound silly but check the coolant level. I know it has a sensor but it don't take two mins to check. That's how I knew my felly needed coolant when it did not get warm inside.
