The check engine light on a 1999 Cadillac DeVille can be reset by disconnecting the battery for 30 seconds. The light will immediately come back on if the problem still exists.
I have a 2000 Deville DTS. The battery is located below the back seat. Just pull up the seat (not back), and you will find the battery.

The voltage regulator on your 1997 Cadillac Deville, is located on the top of the alternator. Some aftermarket alternators have the voltage regulator, on the back of the alternator.
They might be locked.
