06 Cobalt Headlight Issues

I have been having problems with my headlights lately. I have looked through forums on here but cannot find a solution. Here's the issue: the passenger side low beam is working but the driver side low beam is out. When I switch to high beams, the driver side high beam comes on but the passenger side high beam won't. And the DRL's are completely fine. I have checked for frayed wires all along the harness, I have checked all the fuses, I have even replaced the bulbs. What could this issue be??

But DRL's are the amber lights on 06 right. They have nothing to do with headlights. A little late tonight for me but tomorrow I will look up the how to check headlamp filaments on this forum and will post back.

I can't find the previous post so I will re-post the testing procedure. Here are the fuses in question.



On top of the fuses there are test tabs seen here.



With a test lead as seen here connect alligator end to boost (or jump)post and with key out of the ignition take the test lead pointy end touch each fuse tab like shown here. There will be a little spark, don't worry. This will send power to each individual headlamp filament. Park against a garage door if you are alone so you can see the light come on. Easier if you have a friend helping.



Move your lead from fuse to fuse and verify fuse,wiring and filament all at once. Best way I found to check the whole system. 2007 and up you will need to pull the "DRL" fuse first so power doesn't feedback through fuse.


Hope this helps someone.
