my dashboard panel are not working at all such as AC, CD/Radio, map, etc.

Best thing to do is look in the owners manual index, in back of book, and find > Fuses. Then go to appropriate page to see which fuse 'may' be responsible and check that fuse... It'll show the location and function for all the fuses .... That's about all the average DIYer can do! IF fuses are ok, it's a trip to the repair shop more than likely.
