Funny thing happened to me one time,,, I got in my car (Acclaim) and somehow
hit the dimmer switch with my knee on the way in and knocked it half way
between the low and high beam,, don't ask me how,, went nuts trying to find
out what was wrong,, everything worked but the headlights, tail lights, turn
signals, parking lights..but NO headlights after a couple hours of screwing
around... .... and low and behold got in the car did the same thing,, (by
accident of course didn't realize what at the time) and everything worked,,,
Pulled my hair out for a couple days until I did it again and realized what
I did... didn't work, all of a sudden worked...didn't work,,, ah hah.. hope
it is something this simple for you,,
