Hi my honda civi 2006 headlight its no power hiw to check the problems

Hi @sherwinlaja , Which headlight, left, right or both? If one headlight: left headlight - check fuses #13 (high beam) & #17 (low beam) in interior fuse box. right headlight - check fuses #12 (high beam) & #16 (low beam) in interior fuse box. If the fuses check out OK use a Voltmeter to see if there is power getting to the headlight in case it is a faulty headlight connector or bulb etc. If both headlights: check fuse #4 in engine bay fuse box. If this fuse is blown, it should also affect the power windows as well.
