electrical short problem

[soundwave3100]

so im having some electrical problems with my 2001 malibu, on occasion the turn signals\hazard lights wont work, at random times ranging from 30 seconds to 2 days, also, reciently my (abs) light will come on when driving and then next time i start the car car it goes off, this will happen up to twice daily, and usually before the light comes on, my interior lights and headlights dim.

does anyone know whats happening?
Thanks

Get your alternator checked. It should put out 14 volts when running. Looks like it has an intermittent charging problem. Get it checked before you kill the battery.
