Power out to dashboard console

It is a 15 amp fuse located at the passenger side right foot. It is labeled "ACC” for accessory I guess. If it blows again have a high level of suspicion on the power socket. When this gets lose it is tempting to twist it tight which can cause a short. Hope this helps someone else as I'm sure you have either figured this out or sold the car by now.

You need to trace this problem down with a wiring schematic.

There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://www.alldatadiy.com/

I had the same issue, and was told by a high-end mechanic that these specific "computers" just die sometimes and the only thing you can do is replace them, ~$400+ if you get a good deal online and do it yourself, or obviously more if you buy one from a dealer and have them do it. But then, by accident, I ran my battery completely down when I left a dome light on for 3 days. Once I jumped the car, the trip computer worked again, and the entire console was reset, but back to life and working like normal. It's been working fine ever since. I'm not saying run your battery all the way down on purpose, but it did work for me. Perhaps disconnecting the battery, leaving it like that for a couple hours, and then reconnecting and restarting the car would work the same.
