02 cadillac deville wont crank or start the entire dashboard illuminates and everything work when the switch is on seems like it wants to crank but doesnt. I had a problem for years with my 1991 Caddy and kept changing starters for a while. My problem was that I wasn't getting a good read on the security chip in the key. Next time it happens: turn it off, take the key out, wait at least three minutes and try again. Check your manual to see if that is still the procedure. By the way I decided to live with it. Every start is a roll of the dice.
Check for a blown fuse
You wont like it, but it is located in transmission. Transmission has to be lowered or removed to access.
check your antenna belt/fuse !
