Now that you have gotten all these answers from other people, I would
suggest you LOOK at the bulb and see if it is bad. If the bulb seems to be
ok and you can switch the bulb with another and still have the same problem,
it may be like my situation. I had the same problem with my 98 K1500 and
the problem was not either... it seems to be a bad circuit board and the
