I just bought a 2003 E-500 and I've had nothing but problems with the exterior lights. The left low beam headlight, the left license plate light and the left stop light were all out the first time I used the lights. I've tried changing the bulbs, but still no lights. It isn't the ballasts with the headlights, because I've switched those around with no issues. I want to check the fuses, but can't find a fuse chart. Can anyone direct me to an on-line version?
