2003 Ford Focus Question: Heater blows cold air



sljamison20, 2.0L 4 Cylinder SOHC, Grand Junction, CO, February 21, 2009, 06:16

My heater use to blow cold air just when I was stopped at stop lights, or just idling. Now, it blows cold air all the time. I took it to a mechanic, but they "could not duplicate problem." What could it be?

    Try filling out this diagnostic sheet next time you take the car in to the shop, it may help the mechanic find the problem.

    Open Hood and check for Vaccum leaks.
