    Anyone have any insight on where to find JUST replacement knobs for the AC control unit on 458's? Not looking to buy a complete unit for thousands of dollars when all we need is a knob. Any help?

    If you manage to get a print of the exact dimension I guess the cheapest would be to just print the part (the small black circular plastic part) out of a 3d printer instead of ordering the "whole" knob part from Ferrari which I guess will be expensive

    We found a knob in our miscellaneous catch-all bin. Someone was smiling down on us!

    I feel your pain. However unless someone wants to "part" the unit, there's no way of obtaining one.

    how about the knob that you found a replacement for? that one only seemed to be missing a face, and the rest of it was fine.
    do you still have it?

    We had to take it off a useable unit we have here. Unfortunately we can't take another one off that unit.

    No Ferrari doesn't sell just the knob. Without looking it up I know the unit is in the thousands of dollars.

    No wrecker is going to start pulling pieces from the assembly, so new or used, the unit will be sold as an assembly. Remember, Ferrari buys these parts from sub contractors as full assemblies and that's why they don't sell individual pieces - you realize how difficult that would be to manage?

    Ross - don't hold your breathe but try contacting FNA and see if they can get a part from the sub contractor. Again, it's a long shot.

    I hope you aren’t forced to buy a replacement of the entire complete HVAC module.

    When a few of the lights of my 360 HVAC went dark, I was told that I had to buy a replacement module. Fortunately I decided to repair it myself and was able to open the unit remove the circuit board and replace the soldered mini light bulbs.

    But I’m pretty sure you should be able to buy a new knob.

    Or maybe using some glue carefully re-use the old cap

    No, you can't - they are not sold individually.

    Is the old broken cap around or is it lost?

    How much is the new module? I’m guessing $900

    Was a new knob ever located?

    I now have a similar situation in which the fan speed knob needs a new black plastic cover.

    The plastic tabs that integrate into the cover snapped off and I need a new cover.

    We all know it’s a small and inexpensive item but locating one is difficult.

    Have any new solutions been found yet?
