There is a small part called a dim light sender. It is kind of like a fuse. It plugs in and out and is about $20.00. Installing the dim light sender corrected the issue in my car. It was bad because I drove it on a dirt road and it was bumpy.

No dims, just brights? Need lights or fuse? Is there more fuse boxes than the one under the hood?


Have you tried operating headlamps in manual mode, not automatic? Do they work correctly in manual mode?
You have a low beam fuse in under hood fuse box. With headlamps on, low beam, any voltage at that fuse circuit? Even if the fuse is good, if no voltage on fuse circuit, the circuit is still dead.
Any applicable trouble codes? Some of the national brand auto stores will check codes for free.
My info shows second fuse box under rear seat.

Low beam lamp(s) fault detected 2014 kenworth no low beam lights


First check light relay fuse, if ok check battery voltage at low beam light terminal, if ok replace low beam bulb, if no voltage check switch side of relay, if voltage replace relay, if no voltage check headlight low beam switch.

2002 rendezvous low beams don't work. Fuses and bulbs fine. High beams work. Even swapped relays with high beams still no change. Running lights work but low beams don't in auto or manual. What else can...


What about the rest of the lights. The Auto and Manual function should turn the tail lights also. If they work, then it is a headlight wiring problem. If the tail lights are not working either, then it is the auto control module

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

Low beams dont turn on........... bulbs check ok...................fuses under hood ok.............need help


{: ) I wonder how you checked the fuses and the bulbs. Did you check also the HDM fuse 15amp and the HDM relay both at the underhood fuseblock? Turn on the low beam and check for 12v at the LO beam fuses. If there is voltage at the fuses but the low beam ok bulbs won't light, then there's a wiring issue from your fuseblock going to the bulbs.
But if no voltages on the LO fuses when the low beam is switched on, then the problem could be on the HDM fuse or relay, the headlamp switch, the BCM, or even the fuseblock.

03 ion lowbeams wont work highbeams do have


The dark blue wire is the ground wire for the low beams and your pink is the ground for the high beams.

When you touch that wire to ground the lights should come on. If not there is a short/break in the wire somewhere

Double check your pink wire to confirm that it is supposed to be a ground signal.

My son's 93 corolla low beam lights went out at the same time. I checked the fuses and they look ok. Does this happen often?


It is most likely the dimmer switch,check voltage to the low beam lights,if they have no voltage,replace the dimmer switch,if they have voltage to them,replace the low beam lights.

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 headlights dont work,.all other lights are fine though,.is it the fuses or the bulbs? im not sure what fuses they would be,.there seem to be different ones for the same thing


do your flash to pass lamps light when you pull the stalk towards you? If yes, the bulbs are ok.
Do the hig beams work?
Your headlamps have sepaerate fuses for each headlamp and you have a low beam relay and a high beam relay under the hood in the black box.
If everything is out, I suspect a bad headlamp switch.
Check car-part.com and look on page with * for cheapest price.

Your owner manual will identify fuses & relays.

PS, You did not recently instal high current bulbs did you? If yes, put originals back in.

HEADLAMPS

The voltage is supplied to the lamp switch through a fuse. This fuse is located in the central junction box in the left-hand footwell.
When the headlamps are switched on, a voltage is supplied to the high beam/low beam switch and to the low beam relay. The relay for the low beam is located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "low beam", then a voltage is supplied through the low beam relay to the low beam part of the headlamp assembly. The left and right-hand low beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
If the high beam/low beam switch is set to "high beam", then a voltage is supplied through the high beam relay to the high beam part of the headlamp assembly. The left and right-hand high beams are fused separately. The fuses are located in the battery junction box (BJB) in the engine compartment.
