Headlamps not working on main beam dipped ?Work fine on full beam .

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.

Firstly start at main on/off switch then main beam/dip switch failing that have a look at the lighting relays..Good-luck.....

loop the main beam to the second light simple ,find the feed with a meter when the main beam is on ,simple to do but be warned here ---make sure the light has a certificate of homoglonation and a E number in the headlight glass or you could face a big fine for unauthorised modification of a motor vehicle ,also this sort of work can only be signed off by a authorised garage with a Value Added Tax certificate and a inspection to change the cars papers at the local car testing station ,or dont drive in spain as they will impound the vehicle

Have you replaced the lamps? Most car headlamps have separate elements for low beam and high beam. If both elements are broken, there's your answer. I believe also that the high beams are on a separate fuse to the low beams, so check your fuses to make sure it hasn't blown. Hope this helps!

If the 'flash' pull works it will most likely be the switch in the stalk (lever). It should be an easy enough part to get.

Is this both the high beams and low beams that do not work ?

If you checked all 3 fuses with a meter ( with the headlamp in Low position for both low beam fuses or in high for the high beam fuse ), the next items to test are the MFS ( MultiFunction Switch ) and the main headlamp switch ( test not look at it ).

Do you have a good ground in the circuit?

Did you change bulb to see if that helps? Corroded pins on the bulb? If the relay was faulty it should affect both sides.

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.
