Fog lights won't work

Post by 1990BerettaGTZ2.3L »

Don't know about the drivers side but I just bought a set on eBay and just needed the passengers side, took it apart and it had a good bulb, plugged her in and nothing switch is showing to be on cause the LED is lite up, this thing was in a wreck on the passengers side before I bought it and most everything but the marker light and fog were fixed on the pass side, I'm wondering if it didn't burn the inline fuse up that I haven't a clue where that would be any help would be great

Do you have continuity through the wire? I would follow it back from the socket and see where it goes, then test it to make sure a wire didnt get cut or something.

Now that I think about it, those wires go to a relay under the dash on the driver side. Check that

No. My relay was just hanging up there towards the clutch pedal, but I would imagine gm would have had it mounted somewhere

Thank god, finally the lights work I replaced that fog light relay that was mounted to the wiring harness that runs along the firewall to the left of the steering column and it's mission accomplished if anyone else has the same problem when your bulbs are bad let me know cause most likely it's this relay, another thing I notice my headlights were really dim on auto and when I would switch it to the on position on the headlight switch they would get very bright, well I unplugged the bad fog light relay and put it on auto and they were very bright like they should be, pretty interesting the autos must run through that relay it share the same return wire or something but now she's good again like factory thanks Barry for your help
