I noticed the windshield vents always blow warm-like air, differently from all other cars I had which always blew some cooler air from the windshield vents, regardless of the 100F (38C) or 20F (-7C) temperature outside. I know I could just turn the A/C on and problem is solved but would like to understand if that is a problem or MB designed it to prevent glass condensation.

I always liked fresh air coming from those windshield vents better than A/C...just my preference. It seems like I have to keep my A/C on all summer long now.

I have noticed that the cabin air on our vehicle is always warm unless the AC is on. I think the ductwork pick up a lot of heat transfer from the engine compartment. This situation may change once winter arrives and the outside temps drop.

hm, ive been able to go without AC during mild days (70-75*) just fine, seems normal compared to any other cars ive had
