My wife owns a 96 Sunfire 2.2, 5 spd, 114,000 miles. she just recently started to have a very annoying problem when hitting the brakes: the headlights will flicker and you head a "clicking" sound. does anyone know what could be the cause of this? and if there is a way of fixing it without going to an overpriced mechanic.

sounds like your abs system is acting up or she is hitting the brakes to hard...

I've driven the car and have the same problem when just lightly tapping the brakes. I'm going to try putting a new abs module in and see if that helps

yes it sounds like an abs problem. I had a problem like that, i just unplugged to abs module and left it at that. it could possibly be anything from a dirty wheel sensor - to a messed hydraulic brake pump. if cleaning the sensors doesnt help, then i would suggest taking it in to a specialized abs mechanic.
