This is january but the heat setting on the defrost no longer clears the windshield
Its normal if in recirc. mode. or not normal if stuck there.
the heater core is leaking engine coolant (funny smells)
for defrost mode is bad. , due to inop. dampers.
if heat is good to other ports. , then its damper failure.
the FSM covers the tests.
see that here

Sounds like your heater core is bad. Have someone check out the heating system and possibly replace heater core.. that should take care of the fog problem also by enabling you to use the defrost... Good Luck!

same thing happened to mine at 2 yrs. old , the connecting arm on air mix positioner broke. The whole dash had to come out. Part was cheap but labor was huge. This is not a job for the do-it-yourself.

Testimonial: "We have had to attend to this problem, and asyou have said the part cost was small and the labour huge. At least 8 hours to complete."
SOURCE: Defroster will not defrost
it may be, but could be that the a/c compressor is not coming on to remove the moisture from the air. Visit honestautoestimates.com for free estimates on repairs and information regarding any repair.

You probably have a leak in the heater core which is creating steam in the defrost system. So the heater core most likely needs to be replaced.
