Low beams dont work cleaned switch changed bulb..

Did you check the dimmer switch for power ?

Are you sure bulbs are good? If low beam are running lights as well, might be set in series. If one bulb goes out, no light at all. This was the case for a 2003 toyota camry. Was wired in series.

i seen this before, either switch contact gone bad or wireing gone bad

Other possibilities are; the bulbs themselves, burnt or corroded bulb sockets, or a bad headlight selector switch.

if low beams and high beams dont work check the fuse.if only the low beam lights dont work.and bulbs good.i am looking at dimmer switch.

If your low beams don't work you may have to change your high beam- low beam switch. Take your vehicle to any autozone or similar auto parts store who will scan your computer which will give you all or part of the answer on how to proceed.

could be becauce if you dont have low beams and high beams do work once you replace them with new bulbs low beams should work.
