First, what's not working?
If it's the front defrost - Fan inop, mode door inop, temp too low?
Or is it the rear defrost?

Wow! I feel dumb not including that info!! :loser:
The issue is the front defroster. The heater and fan works fine at all speeds. Its when I go from vent to defrost, I noticed that there is no air being pushed out the defrost ducts.
