Fog lights not coming on

[Bryan]

Hey guys I've been having problems with my fog/driving lights on my 91 SHO. I've since replaced the switch and lights. I even have completely rebuilt the original housings since the ones on the car were broken and rusted away. But they still do not come on! Any help would be greatly appreciated.

Change the fuse. Its under the dash to the left of the steering column but its not in the fuse box/panel. Its a seperate stand alone fuse. Remove the kick panel and lower the fuse box and then look above it.

Is it a 15amp fuse? I found one just behind the kick panel in a white plug, but I didn't need to lower the fuse box as the plug was pretty high up. It was almost even with the steering wheel just to the right of the auto lights slider. Sadly though, it was not blown. So what do I look for now?

The fog lights will only come on when the headlights are on, are you aware of that?

They're also driven off of a relay, the switch merely activates that relay.

Hey look! You have two different color turn signal bulbs!

LOL, not anymore. I finally got around to swapping them out the week before the convention.

Yes I did try them with the lights on and still nothing. I guess the relay is next?

Also do both lights need to be hooked up to work to? Because when I tried to get the lights working I only plugged one in. The other is still not connected.

No, it is possible for one to work while the other is unplugged. You might check the connections at the bulbs. If there is corrosion at the little spring clip or if it is bent too much and not making good contact then the light will not work. I had that issue on the way to last years convention. My driver side light stopped working so i went and found a new bulb but as i was removing the old bulb i noticed the spring clip was bent too much. Straightened it out and the bulb started working again.

Thanks for the heads up! Time to start digging through wires again... And a bit of something. I have converted the car over to a Digital Dash. Would this cause problems? I mean yeah, if I hooked up a wire wrong I could see that causing problems, but lets assume its all done correctly.
