headlights wont work on low beam

[andy05]

Big shock last night, headlights would'nt work on low beam (both of 'em) First thought was the headlight switch is faulty. But I checked everything I could, fuses (ok) headlight relays (ok) Fusable link (ok) healight bulbs (ok).

Parkers come on, but when I switch to "headlights" the parkers stay on, and the healights don't come on. High beam works fine. So I think my first guess is probably right (faulty switch), but what do you guys think?

My bet would be the relay. Check where pin 86 goes on the relay and test for power when the switch is on, if there is no power there then the switch is faulty or fuse is blown (sometimes fuses are noticably blown, test it for continuity)

If there is power there, i would think it's the relay so take the plug of the back of either of your headlights and test for any power there on lowbeam, if you have any power there that would outrule the relay and it would be a blown bulb or loose earth.
