Fog lights don't work new bulbs - 1997 BMW 328

Explode ? No. Fail ? yes.
Cover the broken area with shipping tape and order a new lens from the dealer.

If the front side lights are working, then the switch is fine and this is more likely a bulb, wiring harness or connection issue.

maybe the lights are just out. you might just have to replace them.

1. • 1 Open the hood and reach down into the engine bay for the fog light assembly. If you cannot reach the fog light assembly from the top you may need to get underneath the truck to reach it. Remove the electrical plug running to the fog light ballast.
     
   • 2 Remove the bulb. Unlock the fog light bulb by turning it counterclockwise and pulling it straight out of the assembly.
     
   • 3 Slide a new bulb into the fog light assembly. The part number you will need for the new bulb will be located on the ballast or base of the old bulb.
     
   • 4 Turn the bulb clockwise to lock it into the fog light housing.
     
   • 5 Reconnect the electrical connector to the bulb ballast.

The fog lights on most vehicles sit directly underneath the headlight bulbs. The ballast and wiring work just like the headlights, so changing them takes not much time. The procedure to change the fog light is as follows:-- 1) Open the hood and reach down underneath the headlights to unplug the electrical plug from the fog light assembly. Squeeze the top of the release tab and pull the connection off the bulb's ballast. 2)Turn the fog light counterclockwise to remove it from the fog light housing. 3)Install the new fog light bulb.Then connect electrical plugs properly. 4) Test the fog lights by turning it ON.

Halogen bulbs are brighter and generally draw more current than standard filament ones.
Have you check that the supply fuse has not popped ?

I just replaced the fog light bulb on my 2008 Azera. I went under the car and removed two screws from the protective shield. I pulled down the shield and reached up and turned the fog light socket and pulled it out of the housing, remembering which side the wires were on and removed the old bulb (Don't touch the new bulb with your hand) and replaced it with the new bulb. The job took less then 15 minutes
