Could be the relay which is also in the fuse box compartment. Should have diagram on lid of fusebox. Could aslo be the brushes in the motor have burnt out. Which is located behind the dash inside heater unit?

Thanks for the reply Dave.
Fuse box compartment is all ok though.
The dials on the dashboard don't switch anything on, they just turn without doing anything.
I have gotten under the bonnet to check the pipes going into the car have water running through them.
I undid the bleed screws and the pipes are completely empty, not one bit of water.
Could this mean the system is blocked? Someone has suggested that I use a water hose to blast clean water through the system to unblock the heater components.

Could need the thermostat replacing. Also, yes you could try blowing it through with hose. Just a normal everyday hose. Not a jet wash? Was the engine running when you took out bleed screws?

Good point, the engine wasn't running. Would this make a difference?

If the engine is not running, water is not circulating via pump therefore air is not circulating to escape through bleed holes? If with the engine running you still get no or little water through the pipes then you have a circulation problem either thermostat stuck or a blockage in the cooling system or your pump is not working? I still think your problem is electrical. Your saying the switch does nothing when you turn it . If it was a coolant problem you would get cold air?
