fastar1 - I do have just the defrost but it uses 100% of the climate control power when initially used. I want to use just the fan setting on the windshield without the feet where it uses a few % points of power only and there's nothing for that.
I'll try in a bit, but I wonder if one can press the standalone defrost button (to activate the windshield-only mode) and then select "Fan only" to actually disable the grid heater/AC.
I rarely use the defrost mode as well, mostly out of lack of need unless I'm trying to clear a real mess of ice/frost - I just use the defrost/foot setting with whatever nominal heat setting I need to keep the cabin warm instead, it does the job, but I do understand that if you have it on a low/no heat setting that cool air on the feet isn't always comfortable.
