2001 Cavalier Headlight Problems

Hey all.

I got a 01 that I got about a year ago. When I bought it from the GM dealer I had problems with the lights. Last March (when I bought it) I took it in and they had to replace the front wiring harness due to corrosion. No charge because it was still under warranty.

Now one of the lights is only receiving enough power to light the bulb a dull yellow. Other light works fine. Also, after you turn the headlights on the service light pops on.

Anyone know if this could be another deal with the harness again? Maybe its just a loose ground or the DLR module. Anyone had experience with this problem? Any help would save time. Oh, I changed the bulb already. Still didn’t help.

Thanks ahead of time! :)
