most times ther is a short in the circut. maeanig that a wire in the circut that is supposed to be hot at all times, even with engine off, is connecting to ground(body or frame of car) and battery is constantly draining.
There could be several reasons why a 1993 Pontiac Bonneville keeps dying. A couple of reasons could be a dirty air control valve or bad spark plugs.
the battery is flat or its to old
You could have a short from the controlls to the fan
A partial earth
Are the battery wires corroded? If they are, they may not be getting a good connection.
You could try changing the transmission filter and the fluid.
Could be the fuel pump, fuel pump relay or fuse
could be one of the coil packs went bad
your alternator ain't charging your battery or a bad connection draining the battery
Had the same problem. Bought a re-conditioned alternator, turned out it was bad. Usually if battery draining, it's alternator or battery or both.
could be alternator or charging circuit or could be anything got to do with the battery when its draining out loose connection terminal
depending on the year I have had issues with a 1990 and a 1992 grand caravan problem was the light in the glove box the contact would turn the light on periodically draining battery
