I have an '05 T&C w/ 57k miles, with the multi-DVD changer & navigation sound system. Yesterday while driving the radio went off, I had to cycle the power switch and it came back on just fine....then I noticed that the steering wheel controls would not function. I shut the motor off and started it again....WA LA it was working again. The next time the engine was stopped and started it would not work again, shut engine off and back on....WA LA they were working again. Then later in the day while driving it stopped working again AND upon turning engine off and on again it DID NOT work this time AND has not worked since. I checked fuses and they seem to be ok....what about relays? Any other ideas?
