Check relay #46 in the underhood fuse panel, check for corroded contacts first, if clean, replace relay.

Right lowbeam headlight out, bulb not bad


This is not a very reliable answer but my right headlight went out as we'll and before I bought a bulb I talked to different guys at work, they suggested giving the headlight a good solid tap on the outside and sure enough it came back on. Hopefully this might work for others as well!

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.

I have an 06 pt cruiser and my lowbeams will not work. I have changed bulbs and I have checked all the fuses. I tried to install a H.I.D kit when the lights started flickering then went out. Please help.


this sounds like a bad head light switch, you have replaced the bulbs and all fuses are good then i would say try the headlight switch. there is testing you can do to make sure thats the problem but you will need a test light and also a assume the highbeams work. this is a common problem when the headlights start to flicker its due to a switch most times, if was just one light then i would say to check the wiring to light but as its both then i would start with a new or used headlight switch.good day

I got a 2004 chevy trailblazer 4.2l. DRL/lowbeams don't work. All other lights (park lights, high beams, turn signal) work. Driver side DRL bulb blew. Both went out at the same time. Replaced both...


If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

I have a 1997 outback and I have no low beam headlights. any clues?


The dimmer switch on the stalk usually operates a relay in the fuse box.
It could be the dimmer switch, relay, lowbeam fuse, or odd coincidence both lowbeam filaments went out.
Use a test light and work backwards.

Lowbeam head lights dont't work after changing bulbs


{: ) For the lowbeam headlamps, check these fuses at the underhood fuseblock:
LO HEADLAMP LT 10amp
LO HEADLAMP RT 10amp
HDM 15amp (main power for the HDM relay. Important)
Voltage is always present at the HDM fuse. When you switch on lowbeams, voltage should be present on the LT and RT fuses. Otherwise check the HDM relay or swap it with another known good and similar relay.
Check the two fuses again for votage:
If voltage is now present, proceed with wiring checks, checking for open wiring going to the bulbs.
If voltage is still not present on the two left and right fuses, but the HDM fuse and relay voltages are okay, you may be having a bad fuseblock.

Where is lowbeam reset button on 2006 forenza ? Fuses good,lights good,switch/signal & light good (both lowbeams are out).


You should probably start by changing the bulbs. No... they didn't both burn out at once. You might have driven a month with only one, and didn't notice untill the second one went. Just check in the socket with a test light. If you have power, you should have lights. If you don't have power, your switch isn't as good as you thought, or you checked the wrong fuse.
