My 99 Taurus heater isn't working right. When the selector switch is in
one of the two heater options or in defrost, no hot air seems to come
from the vents. On the other hand, if the selector is on vent or AC,
heat will come throgh when the temp dial is in the hot position.
Given the fact that some heat comes through in some conditons, I don't
think the heater core is plugged. The fan motor runs.
This is a 99 wagon, 3.0 fi ohv. Any solutions?
