I have a Ford Ka 'W' Reg. Had a problem with it over the summer where the heating controls would only blow out hot air regardless of the temperature setting, so I changed the heater control valve in the bulk head and the problem was solved.
Now however, I cant get hot air, only cold! Any idea what the problem could be?
A smaller separate problem, when I turn the rear wiper on, it doesn't work. But if left on, after 10 minutes or so it will just start working! The rear demister doesn't work either. (should I just scrap the car
I had the opposite problem with a fiesta. Blowing only cold air, changed the control valve from ford dealer, then only blew hot air. Changed control panel and made no difference. Bought another control valve and that cured the problem. The 1st part i bought was faulty! You can check the valve by connecting it directly to the battery terminals. The valve doesn't stay open or closed it pulses constantly to let varying amounts of coolant into the heater matrix.
