I have a 1996 ford fiesta LX, the heating is working in the sense that the air blows out on all the settings, but the air is cold. What is wrong and how do I fix it??
Sound like the water control valve that controls the flow of hot and cold water to the heat matrix.
There is a valve underneath the bonnet up near the wiper motor with two pipes leading into it and two pipes leading out.
Its probably this costs about £60-00
