Hi

Is the heater providing cold air regardless of the switch position? Does the blower still work? It could be a problem with your heater matrix. You may have an air block in the system which is preventing hot water from the engine circulate through the matrix. A coolant flush and change would solve this (easy and cheap). Is the engine operating at usual temperature? It is possible that there may be a fault with the control valve on the heater.

The fault with your heater is

the heater control valve witch is located in the

engine compertment bulkhead near wiper linkage

easy to change

Thank you to Waggers and Brian for their useful contributions. Norman the Dog obviously still at the stage of learning how to use the heater but thanks anyway Norman.
