AC noise
On my 2018 450 I started to notice a sound coming from the middle two front vents. It sounds like water bubbling. Not affected by turning the two vents off. Sound disappears when I turn the AC off. Any ideas?

Is the A/C evaporator drain clogged? There should be water dripping on the ground as I'm sure you know.

It was a matter of time! Heat/cold can not be modulated. It’s either cold or hot. I can’t get the air temperature anywhere in between. Suddenly happened today. Any ideas before I drag it off the dealer? Tried all sorts of settings, ac on/off, auto, air distribution etc. No luck.
