2003 F350 SC 4x4 5.4L. I was driving last night, "dusk" had my headlights on and realized my dash lights were out. I replaced the headlight switch last year and all has been good. I got home and found the cluster fuses #35 and I think #42? were probably bad, I didn't put a tester on them, I just swapped out the 2 fuses, both 10amps. Great I had dash lights and I had tail lights again. Jumped in restarted to move truck over and no dash lights but had tail lights. I got out leaving the truck running and I had dash lights again. I pulled the headlight switch, all looked good, no melting in the plugs, and no heat. I pushed on the instrument panel with my finger tips and the dash lights started flickering, backed off and they were fine. So I'm guessing there's a loose wire? or connector? anyone have an idea or is the cluster going bad? I also lost the function of the fog lights, but that may be a fuse, I haven't looked yet. Thanks for any help here.
I pulled it all apart and didn't find anything wrong. I re-seated the connectors on the back of the cluster, I looked over the headlight switch real good, I didn't see and burning or melting, although the housing for the smaller connector did look to be a little misshaped, so I figured maybe a loose connection there. I re-seated it nice and tight and wrapped it with electrical tape. Put it all back together except I left the Sony after market radio out of it, it's a piece of junk anyway. Everything works, all lights, even the fog lights decided they wanted to work too.
When driving at night on long dark roads, dim your instrument panel lights down somewhat and you'll notice the road ahead is much easier to see just after a few moments.
A bright instrument cluster light will cause your pupils to restrict and you can't see ahead for animals, debris, etc as well.
