Main beam not working on my hyundai accent coupe

Hi ,Check the light bulb,see if its seat in the seats properly 'for earth' and the light terminals for dirts ,grease,or corrosion.clean if needs to.I think its a Earth problems

the fuse could have blown, & by the fuse blowing it could cause either the relay to become stuck or damaged or the light main circuit breaker could have been damaged, all these details & the individual locations can be found in your vehicles owners manual. best of luck.

Get a schematic and trace out the power source to those devices not working.

It sounds like a blown fuse. Are you checking them with a test light? And have you located all of the fuses. there will typically be a fuse box under the drivers dash area, and one under the hood. have another look Im certain you'll find a blown fuse. Good luck.

the accent does not have a v6 eng. but if it is an accent, with power locks, sounds like a bad power door lock actuator.

have you checked all you cars fuses as one of the fuses may have burnt if so have an auto electrical tech check it out

Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.

DEPENDING ON TYPE OF TYRES IT SHOULD BE 2.2BAR LOOK ON THE TYRE PRESSURE IS PRINTED ON THE TYRE

It may not be the switch; most hi-lo changes are via relay to prevent the higher currents from flowing through light-duty switches.

Locate the relay cluster (it might be near or with the fuses) and if they aren't marked, pull wach one of them and plug back in several times to wipe possible corrosion from the blade contacts.

If they are marked, look to see if the same relay is used elsewhere (part number should be visible) and swap them temporarily to see if the relay is at fault.

Some vehicles will use separate relays for hi-lo beams and another for flashing since that often turns on both beams momentarily.

Lihgting switch must also be checked
