Everything was working fine then all of a sudden the defrost mode quit working.The heat mode will work thru the dash vents but when you try to use floor mode or defrost mode nothing happens. In a nutshell the dash vents are the only vents working.

The mode doors are operated by an electric actuator that could be your issue but on this car the entire dash has to be removed to access it.
