Stupid Defrost question

Loving my truck so far, but does anyone know a way to keep climate control on auto while using a little defrost?

I like everything about auto, but the front windshield slowly starts to fog up in wet/cold weather! The second I turn on the defroster I lose the lazy awesome auto and am in crappy manual mode, truck gets too warm, etc etc

First world problem??? Is there a fix? Breathe less?

Do you have Auto and the AC on? Need the AC (even if cold out) for defrost to work. Mixer will still give you warm air. AC will pull humidity.

I'm not sure that you can have Auto on without AC selected in these trucks, I know some vehicles you can. I leave my AC on all year round.

I've been wondering the exact same thing. Especially after 7 hours of those conditions coming back in that lovely rain/sleet the Saturday after Thanksgiving. Didn't think to try kicking on the AC rather than the defrost.. Personally I dislike defrost, as it tends to dry my eyes out with the air blowing up the windshield.. The day someone invents a front windshield defroster like the rear window has but doesn't give you the lines - I'll trade the truck.

Interesting comment about the AC. May have to give that a whirl. Thanks
I'm a little disappointed more "defrost" isn't directed to the windshield when using the remote start. When I jump in truck I have to hit the defrost button to expedite the defrost action and there is a noticeable difference in airflow to the windshield. I drive right into the sun so any frost is a killer.

I've noticed the same.. truck is all nice and warm, but the defroster has barely started working on the windsheild.. but the rear defroster is on, and the mirrors are clear....

Leave Auto and temperature selected, with the AC button on for defrost is the best way to keep the cab nice and clean of foggy windows for sure. Be sure your air return is not on. This constantly recycles the old air, which gets damp.

for remote start, is your climate control set to Auto or last setting in the remote start settings? In Auto, it will heat up the cab and run the defrost when you remote start, but only if the cab and outside air is cold enough. In Spring and fall I use last setting and leave the heat on Auto, AC, no recirculating and leave it set to HI when I leave the truck if I am thinking I will want to remote start in the AM outside.

I will also advocate keeping your AC on. Not only does it remove/pull moisture from the air, i.e., removes condensate/fog off your windows, but it also does something most folks don't think about- it keeps your AC compressor & seals lubricated to function properly. The same could be said for driving in 4WD from time to time; it keeps everything lubricated and reduces friction.
