First, when the check engine light comes on it means the computer has something to tell you in the form of a code. You should have the computer scanned, not disconnect the battery to reset it. As long as the computer detects the problem, the light will keep coming on.
As for the lights and buzzer, they're controlled by the body control module, which is a separate computer from the powertrain control module. You could begin by checking all ground circuits and wiring/connectors. But these computers in Chrysler/Dodge have known to go bad. If all else fails, swap it out.
