How to Repair Mercedes Fog Lights

1. Park your Mercedes on a stretch of flat level ground and engage the parking brake. Turn the engine off and let it cool for about 20 minutes.
2. Crawl under the front end of the automobile and go the the area directly behind the malfunctioning fog light. Remove the dust cover to gain access to the fog light assembly. Use a Flathead screwdriver to pry off the rubber cover and lay it aside.
3. Check the wiring harness. If the Mercedes has been in a minor fender bender there is a possibility that the wires could have come lose. The plug should snap into the fog light assembly tightly. If it has come lose snap it back in and then test the fog lights. If it still doesnt work, completely unplug the harness to access the bulb.
4. Give the bulb a quarter turn to the left to remove it. Insert the replacement bulb. Reassemble the fog light by reversing the above steps.
