Why is my instrument cluster lights and turn signals out on 1984 380sl Thefuse is not bad.?

Answer 1

You can try replacing the bulbs (get at autozone 2 pack for like $4). Pull the cluter out (it is just a pressure fit. Easiest to pull the steering wheel off but not necessary). replace all the bulbs and clean the glass and replace the rheostat while you are in there (ebay about $10). Also check the ground wire to the rheostat.
