good afternoon my name is ***** ***** I will assist

the first thing to do is check the obvious, the bulbs and be sure they are good. check the connectors behind the bulbs for any damage or corrosion. I will attach a wiring diagram foryou to view as you may have a bad headlight switch.

Roy

make sure you check all fuses in the diagram with a test light for power

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
