Driver Side AC Knob not working

[E90rw]

I have done a bit of searching with little avail...

The driver side knob that adjusts the climate control seems to be completely on the fritz... before last night turning the knob would make the temp wildly jump around and then ultimately land a temp and then not change...

As of last night I turned the knob to the warmer side and the temp jumped to 61 and now seem to be stuck on 61.

It looks like i can replace the AC head unit for about $75 via ebay - do you think that will fix the problem or is there something else I should look for before buying another controller?

thanks!

Did you try something simple first? Maybe pull a fuse for climate control or dash units and then put it back, or disconnect the battery for an hour or so and reconnect it? Start simple, work towards complicated, and maybe somewhere in the middle hit it with your fist and see if that fixes it.

I will try all of the above - ha - thanks.

I found one on ebay for $50 and bought it...

Ok. Good luck.
