Do you mean Fuse 17 or Fuse 28? There are two that control the windows.

Ok I started to go over the window issue forgot it check the fuse number again but when I open the passenger door all the window buttons light up and work is this normal ? But the 30a fuse is still blown as I didn't change it yet .

As I said, there are two that control the windows; one with door open, one with door closed/ignition on. If they work when the door's open, then it's Fuse 17 that's blown:

A common cause for this is that the green/black wire on the starter motor has corroded. Try undoing it on the starter and cleaning up the terminal.

Were they working before you replaced the isolator switch?
