The Heater on my 2000 ford fiesta is only blowing cold air?

Its your heater control valve. I did mine recently. Got a second hand one from a breakers for £10 and took about 5 mins to change.

Does your car heat up. your hot cold gauge always on cold, if so it could be your thermostat.

Hi. Your problem may be caused by a faulty heater control valve. The valve defaults to cold if faulty. The valve is controled by the hot/cold lever inside the car and sounds like the culprit. The only fix is to replace it. I guess you could by-pass it with a length of pipe in place of the valve, but its not something I have ever done, so cannot give any details on its success. I think it is a dealer only part, so it means a trip to your local Ford outlet. Dont forget to make up your antifreeze strength when completing the job!
