One problem related to air bag on-off switch has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
I took my wife's 2007 Jeep Wrangler jk (4 door automatic) to courthouse shell here locally to get the state inspection done (my first time for this since purchasing it on July 1st 2012 from checkered flag Toyota in greenbrier). I received a call saying that the horn did not work, what did I want to do? my wife had said that it had been working the previous week. Well, I said that I want it fixed. The mechanic showed me that the fuse in the fuse-box was not getting any power and they needed more time to troubleshoot it, so they kept it overnight, they then incorrectly said it was a simple relay which they would order and receive later that second day, and they finally figured out that the air bag and the horn were incapacitated due to a faulty $269 airbag clockspring assembly which had to be special ordered from a dealership, so they ended keeping it over the weekend, the steering wheel had been disassembled and would cost more in labor to reassemble. Another option given that he explained to me that he could run a jumper wire to a pushbutton switch to make the horn work but the airbag would not be guaranteed to function as needed in an accident. I made the safe decision to have them replace the entire assembly. I was quite upset though to have to dish out $389. 75 total for parts and labor. I have the receipt to show it in the event that Jeep ever decides to recall that flimsy and unsafe assembly. There seems to be many complaints lodged regarding this same issue online. Considering that this issue not only affects the horn but also the airbag system which was unknowingly disabled for a week or so, the safety of the driver should always be paramount. Thank god that my wife did not have an accident, the airbag would most likely not have deployed. I will be taking this up with Jeep.
