2006 H3 Both fog lights just stopped turning on.

[CaddyStrophic]

I replaced one bulb, just to see if they both went out miraculously at the same time. No luck.

I checked the fuse for the fog lights and it was good.

I swapped the relay with a good one and they still won't turn on.

Anybody have any issues with their fog lights? Switch go bad? I'll check the wiring this friday to see if I can find the culprit.

Make sure your high beams are not on.

Parking lamps and/or low beam must be on for them to work. When hi beam are on they shut off.

Unknown about 06 , but my 08's are the only lights on when it's in park and the headlights go on when you shift out of park . That being said I would also check the main light switch too .

The brights are not on. Not the bulbs, fuse or relay. I guess I'm going to swap the switch.

When you turn or fog light switch on, it sends a signal to the BCM (Body Control Module). This along with the headlights being in Low Beam mode, tell the Fog Lights to come on via relay 69 engaging.
First, take a volt meter. Remove fuse 24. Turn your low beam headlights on. Push your Fog lamp switch on. Take your volt meter and put one lead to battery negative or a good body ground. Place your other meter lead to one side of the number 24 fuse holder. One side of the fuse holder should have 12 volts when Fog Lights are on. If so, from here back through the switch etc. is good. If OK here, there is a inline connector between the fuse box and the fog lights. The connector may be undone or dirty. Start tracing the wire back from the lights to the fuse box till you locate the connector.

Thanks, RadioMike. I've been swamped at work and unable to work on it. I'll do that this weekend and see if I can find what's wrong.
