Jordanc Posted July 10, 2015 Share Posted July 10, 2015 I own a fiesta and last month my heater began to only blow hot air. I bought a new heater control valve and replaced it and it worked normally again. A couple of weeks ago it began to only blow hot air again. So I got another heater control valve and replaced it. But now the problem has arisen again and I'm really confused on what's actually wrong with the heater. It continually blows out hot air even when set to cold. When the ignition is on the heater blows out cold air. Any help would be appreciated as I don't have a great knowledge of cars. Many thanks.

jeebowhite Posted July 16, 2015 Share Posted July 16, 2015 Does the blower work correctly on positions 1,2 and 3? Quote Link to comment Share on other sites More sharing options...
