headlights not working

[ianv72]

hi ppl my s12 is booked in 4 mot tomorrow but the headlights aint working , they were working on sidelights , main beam on both and dip on the off side but not near side . on dip i had a relay clicking so i switched the relays but near side still didnt work so i switched them back & now neither of them are working . the bulbs & fuses are all fine . we tested the current coming through to the headlamps & it is minimal . any ideas ? do you think its just a question of replacing both relays .?
