ok, i got some goofy things going on with the lights on my 87 s10. the front right side parking lamp/signal is very dim, so u can barly see it, and the headlight also does not work on that side, (i think its an electrical problem, not bad bulb but havnt comfirmed that yet) and now the other head light just stopped working. also, the dim marker light i mentioned, when u turn the hazerds on, its bright and works fine, im guessing bad ground some place. wear are the grounds located? thanks guys!!
