When you say the alternator was just replaced, do you mean right around the time this all started, before, or after. If it's before or right around the same time, it could be a bum alternator or a bad/missing ground, broken wire when the alternator was reinstalled.


You say your door locks are acting up. Maybe your auto lock keeps trying to lock your doors and your power door lock solnoid is dead shorting out and causing a powerfluctuation. I know this is a long shot since it should be poping a fuse if this was the case, but who knows. Try finding your power door lock fuse, disconnect it and go for a drive to see if the problem goes away.

Since your lights are dimming, your charging light is comming on and you've had alternator work done, I'd suspect a charging system problem.

Something else. Do you have a remote start on your vehicle? Remote starts are infamous for producing weird electrical gremlins when they go for a crap.
