I suggest that you bring your car to the nearest auto shop as you might end up damaging it as there are some wiring you need to be careful about. It won't cost that much to have a pro take care of it.

Rod is correct...any engine needs fire, fuel, air, and compression..I always start with fire, if you have it then move on to fuel...95% of the time the problem will lay in those two. Once you figure out what it isn't getting, then work on why. Newer cars have a lot of computorized stuff that require specialized equipment and knowledge.

You'll need to use a meter to see if power is reaching the rear door switches. If not, it could be a broken wire or a bad master switch in the driver's door.

Some cars if you disconnect the battery more then 30 secs you got to put a code in the radio to play it again. They probably have the code written in your Car Manual if not you got to take the radio out and find the serial no# on the back of the radio. Write it down tell the dealer it and they should tell you the code.
