All gauges quit working. Can't adjust temp or use cruise control. This happened about 2 years ago, took it to dealer and they said the diagnostic was fine, but they would replace the whole computer system (and not guarantee that would fix the problem). I declined! I replaced the batter and all worked well until two days ago when the gauges quit again. At one time I pushed the A/C button and the gauges popped on and worked for about 10 minutes. Off again. Not the fuses, they are working fine. I disconnected the battery for an hour and the problem did not resolve itself.
