Question about 1999 Cadillac DeVille
Not sure your anti-theft system has activated. You have the Passlock II system, and jump will not deactivate. Suspect your battery is low or the terminals corroded. Recommend you check the charge on the battery and clean/tighten the terminals. If the battery is low, you may have an alternator issue. Let us know what happens.
