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

Lowbeam headlights wont work, brake lights are out and check engine light is on...changed th dimmer switch, no luck


For the low beam problem, Swap relays 45 & 46 in the underhood fuse panel. Relay 46 is for the Low Beams. If that fixes the light, replace the relay that cam out of position 46.
Since the high mounted brake light is working, that indicates that the brake switch is good. You need to check the bulbs in the rear tail light assembly, if they are good, check fuse #34.

Low beams stopped working high beams work fine


Either both bulbs are bad(I've seen it before) or your
dimmer/headlight switch is bad. If you can without pulling the bulb, pull plug from the light. If it's a 4 lamp system pull the low beam. Do this on the left side as the right feeds from the left. With a 12v test light, check for power. (with lo beam on) if you have
power, change the lamp, if you don't it's most likly
the dimmer switch at the steering collum.
Hope this helps Good luck

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

My left headlight highbeam light works and the lowbeam don't why


the filament on the low beam burnt out. but the high beam didn't. You have a filament for each. 1 for high beam and 1 for low beam in the same light bulb. You need a new head light.

Low beam not working


is it only one headlight that the lowbeam won't come on or both? If it's only one headlight it is most likely just a bad bulb.
