The way you phrased that, I'm not sure if you understood what the other respondent meant by "pops". When you press the automatic button, if either of the manual fan control buttons (above and below it) is pushed in, the manual button should pop out when the auto button is pushed. The auto button doesn't stay pushed in like the others when it has been pushed, it's a momentary switch. Neither does it pop out when one of the manual buttons is pressed to take the system out of auto mode for fan control.

If you do need to replace the unit, auto climate control units new were nearly $400 last time I checked. I would suggest you put a 'WTB' (want to buy) posting on the Mercedes Used Parts for Sale subforum (accessible off the main forums page). Lots of folks have parted out w123s over the last few months so someone probably has one lying around for a more reasonable price. I would recommend that you get a unit out of a w123 -- the early w126 series unit looks identical, and some people say they have interchanged them, but technically it isn't the same. (The w123 part has 123 in the part number.)
BTW, sorry if I came across like a hard*ss in my reply yesterday to you about including model info in posts... likewise apologies to querty for snapping at him. Three days of meds for lower back immobility tends to make me snappy (and causes me to make typos, as querty was pointing out).
