ya its is prolly the bulbs, open your hood. look behind your headlamps, some have covers for the low beam and high beam. if there are covers turn on your high beams so you will know which bulb is your lowbeam. if you can unplug them. after cover is removed and you can acces the bulbs. they either twist out, lefty lossey. or they have little metal retainers that you have to move a certian way before you can swing the retainer out. its like a door you just have to unhook the proper side of retainer and the other side will be hinged. use a flash light and look at it close. good luck

clean the computer lead interface. my buddies car did the same thing, we cleaned the computer leads with a good eletronic spray cleaner and it fixed the problem.

A possable culprit may be your High / Low or dimmer switch. All the power to your lights are controled through that switch.

Testimonial: "It appears that is the problem, the book says to remove the steering wheel to remove the switch. I broke the wheel and now I'm in deep Do Do."
