Missing Vent Control Knobs

[derek]

I have an 83 528e and I have been looking for online for a while for some replacement parts for my vent controls. I haven't had any luck so far. I am missing one of the black knobs and the red plastic filter type thing that changes the led color. Does anybody know where I could get one? Would the best thing be to go to a parts yard with a e28 and get the part? I have never really been to a parts yard before, but I just might have to go this weekend.

Since you guys were so responsive to the first questions. I guess I will ask another question. What exactly does the button (on my 83 528e) do that is under the steering wheel a little to the right. I figured out that it locks the windows, but I all ready have alock on the center console. Does it do anything else or is it just a window lock? Kind of a strange place.

under the steering wheel a little to the right

can you be more specific on the location? under the steering wheel? where? on dash? on wheel itself? any symbols/lettering on it? I am not familiar with this model but I may be of some help.

That interior is similar to mine, but those pictures don't show the location of the button.

It is on the dash. Vertically it is below the level of the where the steering wheel attaches to the dash. Horizontally it is between where the steering wheel attaches to the dash and the where the radio is. It is really hard to notice, I had my car a couple months before I even noticed it. It is on the part of the dash that slopes back toward the front of the car. Kinda down by the drivers right knee. There are no symbols on it. There might have been at one time but most of that kinda stuff is worn off on my car.

I attached some edited pictures that might help. I couldn't find any good ones on the internet, but these are the best. It would be easier to see if I had a picture directly looking at the dash and not side views.
