2004 Low beams not working

[Jetsitter]

Driver side low beam was burnt out. I replaced the bulb with a new one then no low beams would work, high beams work. Turning on manual switch and I checked fuse 7 & 10 fuses which were okay still no lights. Could it be the low beam relay? The passenger side was working. Do they only come on when it is dark enough as I can't remember if they are running lights and worked in daylight?

Sounds silly, but did you replace the bad bulb, with possibly another bad bulb?

If no, then it's either your underhood fuse block or your headlight switch......

Manually turn the high beams on.....they are on....now switch to low beams...all lights off?

If yes, give the underhood fuse block a whack with the side of your hand....also try tugging on the main harness coming out of the fuse block...

If that doesn't work, go to the passenger headlight......the two wires to the low beam are orange(power) and dk blue(ground circuit)......get a jumper wire and ground it......now take the other end and back probe it into the low beam socket, dk blue wire(or skin off the insulation just to expose the wire and touch it with the grounded jumper wire)....do both lights come on now?
