There is a valve that the 2 heater matrix pipes go through on the bulk head. This is what the fault could a. Its a common fault on the mk4/5 fiestas. I think the valve is about 45 quid from a local motor factor.

as said normally the valve but i have change one switch panel before that was faulty. I'm sure its the hole bit with the fan switch, heat, direction change knobs and air con switch.
