I've been having an odd problem with my headlights.

when the car is off, and the key is in the "run" position, both headlights come on, full bright no problem, however, with the engine running, and the key in the same position, the headlight on the driver's side is at half brightness... anyone have any suggestions before I rip things apart to diagnose the problem?

 

it may be the daytime running light modual.
check the connections going into it for corrosion. [img]graemlins/thumb.gif[/img]

 

and where would I find that on a 93 cavalier??
