i need to get at the heater switch on my fiesta Rreg?

Question

that is the back ,im not sure if its the switch or the matrix as it will only blow cold air it seems to be getting heat from the engine and i wondered if i could get behind without removing the whole dash

Answer 1

Turn on ignition on full & turn the heater control swith if it comes on making a noise its not the switch, I thought the heater matrix was under the bonnet on a fiesta,under the scuttle pannel??Check the water/coolant level in your radiator header tank and top up with twice boiled or distilled water. or heater valve! someone else had the same problem..
take a look at all these answers too, might help you,

Good Luck!

Answer 2

You may have an air lock.

Set the heater to hot position.
Do the hoses that run to/from the engine and heater feel hot?

You could try running the engine with the radiator cap off, for a while. Squeezing those hoses may help circulate the hot water, and purge any air in the system as well.
