Hi, my name is ***** ***** i will assist you. Which air filter did you change, the engine filter or the cabin filter?

Customer: replied 8 months ago.
The air filter under the hood not the cabin filter
Customer: replied 8 months ago.
No its fine
Expert:  Joshua Haynes replied 8 months ago.

I gotcha. And you say that the air is getting hot but only the bottom half of the windshield is getting cleared? Do you mean that there is still ice on the top or it is just foggy?

Customer: replied 8 months ago.
It's just foggy

The vent has been kicking hard and the air is hot but it will only defrost the small area where the air comes out of
Expert:  Joshua Haynes replied 8 months ago.

When this happens, it is usually because the air conditioning is not working properly. I know it seems counter-intuitive but the defrost system sparingly utilizes the air conditioning system in order to remove the moisture from the windshield that causes the fog. Do you know if your a/c is working?

Customer: replied 8 months ago.
Yea My ac works perfectly fine
Expert:  Joshua Haynes replied 8 months ago.

If that is the case, I am afraid that I don't have any idea why the windshield would be foggy with strong, hot air and working a/c. I will opt out and let another expert try to put in their two cents...

If there is a problem this should be covered under factory warranty, I would schedule an appointment with the dealer. You may have a mode door problem that is not allowing all of the air to reach the top of the glass.
