My first thread, just thought I would share my findings since my searches didn't turn up this exact info.

Picked up a '03 EB and several of the steering wheel buttons were inop, the rest worked fine or at least sometimes. After reading on here and other places that these seem to "go bad" I picked up a used set off eBay cheap. Long story short, these has certain functions that didn't work also, seller sent me a replacement used set no charge.

Son now I have 3 sets, one that works well (the last set) but the buttons looked terrible. I decided to sacrifice one of the partially working ones to see if I could tell what failed.

After some trial and error here is what I found:
-the functions that quit working were due to dirty contacts.

That's it. Dirty contacts. And they are simple copper contacts.

All you have to do is remove the switch form the wheel, and get a skinny T8 torx in between the buttons at the top and bottom and loosen the two screws holding the board/switch assembly to the housing, and that assembly comes out. Gently separate the board from the button assembly, and you can easily clean the button and board contacts with a cotton swab and some denatured alcohol.

Bit good sets I have work like a champ now!


Hope this helps someone having the same issue! Takes all of 20 minutes total start to finish
sscharlie, thanks for the info and pics. I have an 05 with failing controls as well. Did you have to remove the air bag to get to the cruise buttons?
thanks for your help.

dano, you might want to try the directions I posted on page 3. It involves using wd40 and spraying the controls. Worked for me and others and we didn't have to take the controls apart. Worth a try.

Yes. But the airbag is held on by two 8mm bolts that come out easily. I didn't even bother to disconnect, just set the airbag on top of the steering wheel column.

I just did the maintenance this weekend myself, and it was worth it! The cruise set speed, accel, and decel work on the first push now instead of 3-4 hard presses! Also my volume controls always goes the direction I press, where before it would occasionally increase the volume when I pressed volume down.

I know this is a year-old thread, but do PULL THE AIRBAG FUSE before removing the air bag, just in case!! I have ONE button not working, will try spraying around it with tuner cleaner before removing. This is a great tip, thanks OP!!

Nice! Thanks for sharing this! I have the same issues on my 05, and was going to have at it once our weather warms a bit. Now I know what I am in for, and what I need. I had a feeling it was dirty contacts by the way it acts, but couldn’t prove or disprove that until I got it apart.

Once I do this, I plan to try Caig DeOxit as my cleaner. I already have it on hand, as I used to do a lot of electronics work at my home shop years ago. Now it’s a staple like WD40. Lol. It works well not only to clean contact surfaces, but also to leave behind a coating that helps inhibit further corrosion.


Again. Nicely done!

I have been meaning to do this for a long time. I have had issues on occasion with the radio controls not functioning properly and only radio controls all other buttons for cruise and temp worked fine. Example - volume down button would change station and various other wrong functions. I replaced the factor radio with a Kenwood and payed for the extra wiring to have steering wheel controls and unfortunately the same problem. I didn't think a new radio or cleaning the buttons would help since the buttons would always work just not perform the correct function and it was a most likely the clock spring. A few weeks ago I decided to give the cleaning a try since my cruise control buttons were starting to work intermittently. I didn't find anything that looked dirty and after reinstall it did fix my cruise control buttons but the radio buttons are still not functioning correctly all of the time. This thread was very helpful and made the cleaning easy. I would like to try replacing the clock spring next but I am not paying over $200 for a new one just to have steering wheel radio controls, so I might try one from the local yard if I can find one.

Has anyone removed the steering wheel? I believe I found a clock spring at the local yard but not for sure what tools will be needed. I am guessing a standard steering wheel puller will be needed and just some basic sockets.

How does the switch assembly actually come off the steering wheel?
I have a 2005 Expy Limited where I have the same issues with the cruise.
