When I first got my car every time I put the defrost on, the A/C would come
on with it. It no longer does that, or at least I don't think it does.

Is the A/C light supposed to come on when I put it in defrost or is the A/C
is some sort of stealth mode? I thought the light did come on, but it's been
months since I last used the defrost.

That all being said, I just had the car in for service recently and I'm
thinking they disabled the A/C + Defrost feature. If that's the case, how do
I turn it back on? Or is something like that in the manual?
