alright, 86 w250. what's happening is when i'm driving down the road at night with my highbeams on, my lights will work fine for about 10 min. at which point they will start to flicker off and on. if i switched it to low beams, they would work fine. as soon as i turn the high beams back on, a few minutes later they will start to flicker again. now, tonight i was coming home from work and found my lights flickering again, so i tried to switch them to low beams and found the switch clicking normally, but lights will not change to low beam. i stopped and felt the headlight dimmer switch to find it warm and smelled burnt inside. so i went to the parts house and bought a new dimmer switch. same thing, cannot switch to low beam. i got home, tore apart the old dimmer switch to find the plastic has gotten hot, but the terminals aren't burnt up, and no water in the switch. i am led to believe there is a wiring problem in the circuit. now, i was wondering if any of you guys have experienced this or heard of this type of problem before and could give me a headstart on this for tommorrow's diagnosis. i plan to look at it on lunch or after work. as always, thanks to those who have taken the time to give a man a hand.
