Steering wheel buttons not working/Horn activates interior lights

Hello, I have a 2004 X5 3.0i with 272 thousand KMS (canadian) and it has been a great vehicle no issues what so ever until now. The steering wheel buttons do not work ( radio, cruise ect...) except for the heated steering wheel. The heated seats do not work all of the sudden and I have no horn. When the horn is pressed the interior lights come on which is strange. I have no clue what is going on as this just randomly happened. The rain sensor wipers donít work any more either and I also had the air bag light come on, which was the first indication that something wasnít right. Any ideas as too what this could be? A short circuit some where maybe? This has all happened within 2 weeks and I have no clue what it could be. HELP!!! I drive a lot and not having cruise is painful!

Suggest: Ignition switch. (My airbag light came on but I could make it go away if I wiggled the key in the ignition.) Clock spring for all the wheel buttons. Rain sensor. Also check the wiring loom on the steering assembly.
Also how old is your battery. An old, low battery can make the vehicle do all sorts of things.

Ditto, the odd electrical gremlins that can be imitated by turning on/off other electrical items...is usually the ignition switch. This is a common glitch suffered by e46/e38/e39/e53 owners.

I made a video a few years ago of this odd behavior in my e38 which shows some of the things you describe...btw there's a good DIY on e38.org on how to remove/install this switch ...the instructions are the same for the e53.

Those are some of the exact symptoms Iím having! I also have loss of power as well... Ex: i will be doing 120km/h and all of the sudden the car feels like it dies for 2 seconds then power is back and this is consistently happening. It o bad that I had to take back roads home in fear that the car would die on the busy highway. My 4x4 light and brake light with the exclamation mark just came on as well both together (brakes are working). And my front wipers are stuck in the middle of my windshield now after trying to use the washers. I will be taking it to the dealer tomorrow, which will most likely cost a fortune but I guess we will see.

If you look at the DIY on e38.org...you can see that it only takes a few tools (which you probably have) and between 30-60 minutes to change the ignition switch yourself. The only reason it takes 30-60 minutes is if you're not familiar with removing the panels from around the steering column etc...so you find yourself being gentle so that you don't break anything. The iggy switch is less than $100 (which is probably less than the 1 hour labor you'll get charged + the part).

Check out the DIY and see if it is something you can tackle yourself if you have the time. Your 3.0 may use a different part nbr than what the 4.4 V8s use...but again, it's in the same location and the DIY procedure should be basically the same : http://www.bimmerboard.com/forums/posts/244045
