My main beam and dip lights not working checked the fuse and the bulbs and cant see that there is any problems with it,

Fuses F15 and F16 are okay?

This says it might be the switch. I can't find relays, so the switch is carrying the power (amps) instead of switching it through a relay.

May not be the bulb or fuse..could be the switch... dipped beams illuminate via voltage from the turn signal...Check your wiring and sockets and grounding . Dipped beams are usually near the bottom front fascia of the car . If there is not a shield there, any debris can cause corrosion, or chafing of wires and connections.

It's possible the "main" lights elements have burnt out.
I believe it's a single bulb per side with both high and low beam elements inside.
Try replacing a bulb and see what that does.

CHECK FOR LOW/DIPPED BEAM FUSE BLOWN IF OK CHECK BULBS

in your headlight you have side light a dipped light and a main beam normally the one bulb has your dipped light and your main beam sometimes the dipped light can go and you need to change the bulb ,even though the main beam maybe ookay

will probably be the switch then.

Hi, the main headlights work through a separate fuse from the full beam. If all the fuses are fine the problem might be that the globes has blown on the vehicle. To make 100% sure that it is the globes, see if you get power to the headlights when the main lights are switched on.

Probably not, the fog lamp relay works off the dip beam power, is there a relay for the dip beams?

hi this may be the dip beam element blown ie bulb req's renew? or check the fuses l/h dipped beam as each h/light has seperate fuses for both dip and main beams CHECK BULB 1ST ?

Clyde,

I've been troubleshooting this same problem on a different vehicle this week, and I can give you the steps I'd take.

1. If both sides went out at the same time, the problem is *NOT* likely to be the bulbs.

2. Check the fuses to see if both low beam lights are on the same fuse. Many cars have one fuse for low beam and another for high beam, so both lights out at the same time typically means fuse blown.

3. If the headlights are OK and the fuses are OK, then the problem is *LIKELY* the headlight switch. In my case, AutoZone has one and it can be installed easily; but in your case, that may not be as simple.

Please post your findings or comments.
