I have a 1989 mercedes 300E. On Friday I went to fill up with gas and after I filled up I wanted to see how much milage I get out of a tank of gas so I decided to push the button for the tripometer and as soon as I pressed it all the dash light, vent lights, a/c - heat control lights, and stereo lights turned off. The head lights, break lights and the dome lights all work fine. I check the fuses under the hood and cannot seem to find any problems (if I am looking in the right spot).

Could someone please help....

Thanks
