Heater failure? or fuse?

[Exia989]

My 2003 explorer decided, as soon as the rain here in Washington decided to get cold and rainy again, to have the heater stop working. When on, it just blows outside air at me, which is rather cold. Im not sure if its a fuse, or not, because in the manual (that came with the car from the factory) i cannot tell which fuse would be the one that would have anything to do with the heater. Im hoping that its just a fuse, and not something more complicated. Does anyone have any ideas as to what to look for?

Welcome aboard!! Try doing a search for "no heat".

Your issue could be related to the blend door actuator. Here are some threads to check out:

Also take a quick look under hood to see if the heater valve is moving when the temperature knob is turned from cold to hot and back to cold. The vacuum line may have been disconnected. I would look here first and also if you do not have the clicking from the blend door and actuator issue. Let us know what you find.
