Need a temp control button for 97 528i

I have a 97 528I that is missing a HOT temp control button. Would anyone out there be willing to sell me one or know where I can get one.

I could also use a new cup holder, but those are on ebay.

This is my first BMW.... I like what I have seen so far.....

unfortunately, you won't find the button separately unless someone save an electronically failed unit but so far, only the buttons seem to break.......
