I was driving home today and attempted to make a call by pressing the phone button. The phone wouldn't activate. After a few attempts I realized that except for cruise control, none of the steering wheel controls were working. Nor were the lights on the buttons lit. I assumed I had a blown fuse or that there was some kind of weird defect. I wasn't able to find any info on this site.
A quick Google search lead me to the Jeep Wrangler site and owners had reported the same issue. Several people had posted that blowing the horn solved the problem.
I walked outside, got in and started the JGC. None of the lights on the steering wheel controls were lit. Nor did any of the buttons work. I honked the horn and the steering wheel controls lit up!!!! I was able to use all of the controls and make a phone call. Problem solved!!! That is the weirdest thing I have ever seen!!! But it saved me a trip to the service department.
Anybody else experience that problem?
