No power to right side (PS) headlight low beam plug socket, new bulb, fuse is good. High beam works, blinker works, park light works. just no low beam and doesn't register any voltage on volt meter.


check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

One low beam head lights will not work, high beam works though


check for a damaged wire for the low beam. Also wouldn't hurt to check the ground wire as the high beam will try and ground through the low beam but not visa verse

Other possibilities are; the bulbs themselves, burnt or corroded bulb sockets, or a bad headlight selector switch.

Low beam head lights not working - The low beams, both stopped working. The high beams work fine. I checked the fuses and all 4 are good. I even swapped the low and high beam fises just in case. No...


if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and grounds.you also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals

2003 Kia Sedona replaced low beam bulbs checked fuses still won't work high beams n fog lights work can u help


IF THERE IS NO POWER AT EITHER LOW BEAM LIGHT SOCKET & YOU ARE SURE ABOUT THE FUSES, SWAP THE WORKING HIGH BEAM BULBS WITH THE LOW. IF THAT DOESN'T DO IT YOU NEED TO REPAIR OR REPLACE THE BEAM SELECT SWITCH, { DIMMER SWITCH } KNOWN AS THE COMBINATION SWITCH, UNDER THE STEERING WHEEL. CAN USUALLY BE DONE WITHOUT PULLING THE STEERING WHEEL. TEST BEFORE BUYING, MAY BE COSTLY. GOOD LUCK , DR.VOLT

Low beam dosent work. bulb is good highbeam works cant find fuse for lights. its not underhood


Hi,
It has been because the lamp bulb or halogen lamp module has reached the end of its serviceable life, not because of any wiring problems. Low beam burns out first because it is on the most. If low beam is lost simultaneously in both headlights, I would check fuse first, then the headlight switch. If low beam is lost on one side only, it is almost always going to be due to the bulb or lamp module needing to be replaced. In that case, replace them in both headlights because the other one will be going kaput in short order, as well.
Most like the low beam filiment is bad but the high beam filiment is still good, try replacing bulb. If replacing bulb does not fix problem then you probably have voltage problems and should check the voltage reading and the plug.
OR
isolate the wire that comes from the headlight switch to the headlamp bulbs for low beam and check to see if there is a short in the wire. You can find this wire by using a test light turn on the key and get a good ground with the test light poke the wire and see if the test light illunimates with the headlight switch on.
check the wires, and check the fuse for your lowbeams. could of blown a fuse on your lows, but your highs will still work.

The fuse box is located in the engine compartment,on the driver's side. Has thumb-screw retained cover.
Thanks for contacting fixya.com
