Tonight as I was taking my girlfriend home in my 1999 Mercedes e320 (W210) I turned on my headlights and my dashboard lights and my A/C control lights didn't turn on with them like they normally do. I got home and noticed that when I opened the door with the lights on there wasn't a chime to turn them off like usual so I check the instrument panel fuses (#4 #7) under the hood and they seemed to be fine, then I proceeded to take off the negative battery wire for about 5 minutes to see if that would do anything and it did nothing so I'm honestly very confused if its just a bulb that went out or if it could still be a fuse but if anyone has any advice please let me know because I do not like not knowing how fast I'm going at night.

 

Hi Isaac - welcome to the forum! It sounds like one of the bulbs possibly went out. I'm attaching a link to our site's DIY tech article on the replacement procedure. Please let us know if you have any questions or if we can assist with any future part needs.
