my heater is only blowing cold air not warm what could it be

lee, January 2005

change the flow and return valve under the bonnet, at the rear off the engine below the wipers. that controls the heat. it consists off two hose,s and xome wires. diy it cost about £20.00 if you go to ford it will cost you...

u filled the radiator up, usually the water in the rad will take the heat from the engine and disperse it through water and air, if there is no water in the rad there isnt enough water to get hot, so there for heater will blow cold as it relies on the rad for heat.

check your temp guage see if its running hot.

or u could have a rad leak.
