i put in new sidemarker bulbs, but they werent working. tried to find the fuse but could not, but then after cleaning out the socket real good, the bulbs are working!!

but i'm still getting "lamp defective" message when I turn the headlights on (position 2). i'm stumped now cuz i've looked everywhere and every other light that should turn on at position 2 seems to be on.

any ideas?
