No eractic behaivor, just either works or doesn't work.

As stated above, my money is on the FSR being the culprit.

i pulled out the control panel unit (really easy, just pops out) and cleaned the contacts. put it back and haven't had the problem since.

Nope the display has always worked. All buttons work, everything lights up, just no fan either heat or AC

Then, have to agree w/Ucrew.

Yep replaced Final Stage Resistor and everything is back to normal. Why doesn't BMW recall these faulty pieces of crap and replace themselves?
