2001 Olds Intrigue Fog Lights Not Working

For Some Reason My 2001 Intrigue Gl Fog Lights Stop Working. The Fuse Seem Good And The Bulbs Are Good. I Have Approximately 41,000 Miles On The Vehicle. My First Problem Was That The Headlights On My Vehicle Would Get Dim And Them Normal. I Changed The Battery Out, Due To Corrosion And A Rusted Broken Positive Post. Seem To Fix The Headlights Problem. But Fog Lights Still Not Working. Please Help!!!

Check the fog light relay. Try swapping it with the AC relay to test the theory...

If your running during the daytime, make sure you turn the light switch stick, one turn up to the first detent, ( I think they call them conering lights)and press the fog light switch on again. At night the fog lights should work when the headlights automatically go on.
