Question Z3 Temperature dial broken

I have a 2001 Z3. I tried to force the temperature dial from cold to warm and something broke. The dial now turns freely and does not adjust anything. I removed the radio to access the back of the dial but could not see what was broken. Does anyone know how to repair the dial. It looks like if this is broken then the entire heating and cooling dial housing would need to be replaced.

This one is a first for me. I have never seen this asked before, not because it hasn't happened probably, but because no one wanted to put it out there. Buy a new or used unit.

Thanks Ron for the info. I can reach in a move the air blending flap by hand and it doesn't stick so I don't know why the temperature control rotary switch was so hard to turn when it snapped. Just so I'm clear on kostverloren's response, I will need to replace the entire rotary knob housing. If so, does anyone have instructions on how to replace it?

Yes Ron I read through it all. I'll have to check and see if the temperature control cable is attached to the bend flap lever. When I looked in I didn't see the cable end so I need to take another look at. I assume that is what you are refering to. That goes to my original question of how to repair it. I'm sorry if I'm a newbie but I was expecting more guidance than RTFM. Other forum answers were pretty specific on how to go about things. Even pictures were provided.

Thanks Ron. That is exactly what I was looking for. I'm sure I'll be able to fix it now. I appreciate your patience and quick response.

Thanks to Ron and the picture of the HVAC control backplate I was able to fix the temperature control arm. I took a small threaded eye lag and cut off the loop leaving a threaded post. I then screwed it into the temperature control arm and it works fines.

Hi, I am new to this forum and have the same issue. I can see that the nipple is broken off of the control arm for the heat. I am confidant that I can fix it if I can get it out - I was wondering if anyone can tell me how to remove the control arm?

Thanks in advance!
