Is there a DIY for replacing Fan and AC buttons on E90 E92 E93?

My AC and Fan speed buttons are worn out. Is there a way to purchase just the two buttons instead of the $500 Whole unit in the pic?

Also how do I pry them off without breaking?

If they are like the radio then they are rubber behind the button the tough a circuit board to activate. More than likely the circuit board and buttons just needs cleaned with alcohol. I don't see how the buttons can "wear out." They look fine in the pic, I assume it yours, is it. As far as disassembling the unit I would suspect tabs and screws. You just need to be careful. The unit is very easy to remove. Just use a plastic pry tool and it pops right out.

Thanks, but no the pic is just to show what I was talking about, mine is in worse shape. The parts places sell the whole unit for:

DASH CONTROL UNIT 3 Series; w/Heated Seats; To 3/13

MSRP Core Save Online Price
$701.12 $0.00 $154.25 $546.87

I'm just looking to see if I could buy the buttons.

Is the issue cosmetic or operational?

Close, but thank you thank you for steering me in the right direction. Non of the U.S. Sellers had one like mine(pic below), but I'm bidding on one from England.

You are correct. I just don't know how to take the dash apart without hurting anything.

Did you ask BMW if they'd cover it under the warranty? This seems to be a dumb way to design the buttons -- white plastic and paint.

If BMW refuses to cover it under the warranty, there are itinerant "vinyl repair" guys who operate out of vans and make rounds from dealer to dealer fixing the little stuff on their used car lots. This kind of stuff probably happens a lot.

Look under "vinyl repair" in your phone book or ask your dealer's used car manager who they use. I've had repairs done on several cars and the cost is quite reasonable. The guy I used had an amazing eye for color matching.

I managed to do something that looked like your buttons to the dashboard paint of my wife's brand new car -- of course she said it was okay, it didn't bother her, and of course it wasn't, it would always bother her and I needed to fix it. I was probably looking at a $1000 repair. The repair guy spent maybe 20 minutes, used an airbrush and the problem disappeared, forever.

It was pretty cheap, maybe $50, and I'd probably try that before shelling out $550 plus a weekend pulling the dashboard apart.

You don't have iDrive, correct? You just need a plastic prying tool. Insert the tool between the dash material and the component and pry. It pops right out. No screws or anything. Make sure the pry tool is plastic and not metal.

Thanks, I do have a set of pry tools, will get to it as soon as the replacement arrives from England.

The unit finally arrived and I installed it. Everything looked great including the harnesses and the unit showing both temperature displays.
Tried the buttons and everything lights up appropriately EXCEPT A/C button! The light comes on when pushed, but no cold air.
Outside temp was 81 and knobs set at 60.....

So much for all this wait and money spent

Thanks for the suggestion,
I may just try that. Take the buttons off the new one and somehow stick them on the old one.

You know, I thought that too, but it was working a few minutes before swapping climate control units.

Update: I figured it out!

After several attempts to get the new Climate Control Unit to work, I yanked it out and reinstalled the old one.
I then put the buttons off the new unit onto the old one.
The old unit, however, started to blow hot air at max fan speed out the rear vent!!!

After a frustrating couple of days of research, today I finally got ice cold AC to work out of the correct vents....

A. I removed the negative lead off the battery which is a bee-otch to get to. Reattached it after 10 minutes.
B. Turned the car on.
C. While the car was running, I removed the CCU with both harnesses still attached.
D. Removed the right side(gray) harness: still no AC, and reattached it.
E. Removed the left side(black) harness: unit and fan stopped working. Reattached it and voila! Cold AC, correct fan speed, and display!

Wooh, I thought I was looking at a $$$$ trip to the stealership.

Interesting. Glad you got it figured out. What made you think about doing that?

Honestly, cause I had tried everything else up to that point.

BTW, my daughter is going to be a TTU Red Raider this fall. I'm so proud!

Mine was replaced last week under warranty because the buttons were peeling. They didnt replace the entire unit, rather the part that is referenced above (about 60 bucks).
