If not and the problem still exists, I would take apart the switches at the wheel and see if the star shaped contacts have slipped out of postition or are oxidized as well.
Thanks. Will give that a shot. Is there a way to remove the wheel cover without taking apart the wheel?

theres 3 bolts at the back of the steering wheel that once removed the whole horn/airbag assembly comes off together.

No repair for a bad switch, need to replace the airbag trim cover.

Rather than disturbing the airbag and cover, check switch operation with an ohmmeter...
  1. First disconnect the negative battery cable, wait a few minutes for circuits to discharge
  2. Remove steering column lower shroud cover
  3. Remove the clock spring connector (white), then check the switch operation with an ohmmeter between Pins#4 and #5.

Hey guys, sorry to necropost, but this thread had something in it that may apply to me. Now I'm not a mechanic or electrically saavy, so bear with me....

The diagram on the first page shows the horn switch being in a dotted-line box called the "vehicle speed controller". Does that also have to do with the cruise control? Both my horn AND cruise control do not work, and it occurred to me that it could be something in the wiring.

Thanks for any tips you can give me!
