SOURCE: high beams wont turn on.

First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

Take a look at this link regarding DRL system. I know it's not exact truck but most of it would apply to yours too. It should give you hints on what to test & how.

Could be the relay for the lowbeams is faulty, if your DRL's are your lowbeams, then your DRL Unit could be bad. Also did you blow a fuse cuz a random surge could blow the fuse

My 2004 madza 3i high and low beam are too low. I have to use high beam to see the road. Is anyone know how to fix it?


This is not hard to fix. Wait until it is dark enough outside to clearly see your headlight beams, then park your car on level ground 20 feet from a wall, fence, garage door, etc. Turn on your headlights (be sure your high beams are off) and open the hood. on the top of each headlight assembly you will find an adjustment screw... just turn the screw with a Phillips screwdriver until the hot spot in the center of your headlight beam hits the wall where it meets the ground.

Both of my low beams just stopped working at once. High beams work fine, and bulbs seem to be good. We've replaced the fuses also, and it hasn't worked. what would cause the low beams to both just quit...


The headlight relay has probably failed. This relay is in the underhood fuse box. There are typically two of the same relays in there, so you can swap the low-beam relay for the high-beam relay to verify the problem before you shell out $30 for new relay.

My low beam lights sometimes stop working i still have high beam and daylight runing lights after a while they come on.2009 elantra dealer can't find problem.


when the low beams quit try switching from high to low and back and see if low beams stay on, if they do it may be the dimmer switch, if that doesn't change anything suspect the headlight switch.

What would cause both low beam headlights to go out at the same time? i have replaced the headlights and they still dont work.


The headlight high/low beam switch assembly.96 Safari has the turn signal stem as the high/low beam switch.Removal of the steering wheel is necessary to get to the switch assembly for replacement.
