Our X5 has a good battery, but will not turn over and the seats do not work but the Flasher does?? does any one have any idea of what could be wrong?

First, wrong forum.

Second, just cause the magic eye is green doesn't mean the battery is good. It just means that 1 cell is good. See if she'll jump.

If it won't jump you have one or more bad cells. It's possible that you can show 13+ volts and still not start because you have too little amperage. Amps are what do the cranking.

How old is the battery? If it's 5 or 6 years old it should be replaced.
