I have an 04 impala ls 75000 miles I cant figure out whats going on with my headlight. The right ones work great but the ones on the left are dim. I tryed changing the bulbs nothing. They were fine and two days ago while I was driving it said highbeams out so I thought I just needed to replace them but their still dim. Any ideas?

Let's try this turn on the head light's on low beam then go to the dim side unplug the low beam bulb. Check and see if you have battery voltage to the orange wire. Then see if you have less then 2 ohm's to ground to the dark blue wire. Let me know what you find.

So both your high beam and low beam are dim on the left?If so I told you on the my last post how to test the low beam side. Here is what I said in my last post.

You would check the voltage with a multimeter set to dc voltage 20 volt setting. The black lead to ground the red lead to the orange wire. You would use the same multimeter set to the 200 ohms scale the black wire to a good ground and and the red wire to dark blue wire and your looking for a reading of 2 ohms or less.
