Headlights

I have a 2001 Sunfire, the lowbeam recently stopped working on the drivers side I replaced both bulbs and still nothing, the highbeams work fine, ive checked all fuses and they are ok aswell, when I start the ignition the dashboard light for my headlights flashes at me multiple times and makes a clicking noise before turning off and the service engine light lights up. What could be the problem? I have also chaged the unti that hold the headlight bulb
