Heat not hot

[absentmathis]

I noticed today that my heat isn’t very hot. It’s warm, and all the settings including idrive are set to hot, but it’s not getting up to normal temp. As a secondary and likely related problem, the auto climate control doesn’t seem to be working. I crank temp up to 84 and put it on intensive but fan speed doesn’t change (at all that I can tell). I can think of a few potential issues including water valve and tstat, but I’m hoping someone might have some insight? FWIW, BMW replaced my passenger airbag few weeks ago and this may have been going on since then. Everything else seems functional but I’m wondering if when they pulled the dash something got left unplugged or damaged. They botched putting the dash pieces back together so it’s going back in a couple weeks, but in the event this is unrelated I’d like to get ahead of it.
