Question about 2005 Toyota Corolla

Low beam headlights don't work

Have changed bulbs, fuses, relays, switch at handbrake, and headlight switch. Lights usually come on when handbrake is released but now will not come on even when light switch is turned to low beam lights. High beam lights work as do turn signal lights and all other exterior lights. Want to replace daytime running light relay but unsure of how to remove it or its location.

    Toyota Ed,

    I have added new low beam headlights. The main question that I have is, Where is the Daytime Running Lights relay located in the car ? So I can replace it. A diagram would be perfect. Also would like to find the relay alot cheaper than the $218.00 that the dealer wants.

    I have a 2000 Corolla. The low beams are very dim. At night the DTRL comes on when I start the car. When I turn on my lights there is no difference on the brightness of the head lights. When I put on the hig beams it is brighter. I noticed in the fuse panel under the hood that the headlights have a 10 amp fuse and the cover says it should be a 15 amp.

    Why are the low beams so dim almost like there is no difference from the DTRL.

    Thanks

    The daytime running lights use the High Beams at 6 volts. The DRL module is not your problem. Are you sure that you have looked at the low beam bulbs? They are seperate from the high beams. They are on the outer sides of the headlamp housing, not real easy to see. Please advise.

    Passenger side bright beam headlight does not come on when both bright lights should be on. Oddly, that particuliar bright light does come on dimly as a daytime running light. All fuses are good. Both headlight relays seem to be ok when I interchange them. Not sure what dimmer relay is supposed to do but it appears to work. Any suggestions?

SOURCE: Low beam headlights don't work

The problem is in the high beam switch assembly which also houses your turn signals and possibly cruise control, and yes, I'm sure. There are some electrical contacts in the assembly which dis-connect the low beams when you put the high beams on. Constant use of the high beam switch will create arcing on the low beam switch which makes the contacts not conduct electricity anymore. The daytime running lights send power to the low beams on a separate circuit. .

The repair is to either replace the assembly, $300 at dealer, $100 or less do it yourself, or take the assembly apart and clean it for free. (2 hours or less)

P.S. If you own a VW, especially around model years 1999 to 2004, there is a rare but devastating problem with engine coolant being literally pumped through all electrical parts of your car.... destroying it. Repair cost = $8,000. It is called coolant migration. Check your VW right now (takes two seconds, literally), and do a two-minute procedure to fix your car to prevent the problem here: http://www.myturbodiesel.com/1000q/multi/coolant_migration.htm

I have no low beam headlights. already checked bulbs, fuses, relay and dimmer switch. can you help?


Before you replace the #46 HDM relay (in the fuse block under the hood) try exchanging it with the #45 cooling fan relay and see if your low beam lights work. If they do, the HDM relay (actually solid state module, not a relay) is bad.

Daytime Running Lights Inoperative 2002 Toyota Camry


[Information] For a 2002 Toyota Camry, the Daytime Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."


2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not burned out. If one burns out, there is a fair chance that the other would have burned out at the same time. Replace as necessary. In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]


My problem was that the test configuration did not have the engine running and parking brake off - Step 1. Problem solved with much thought, repetitive tests on the vehicle and going back to the basics -- what does the Owner's Manual say and where are the applicable fuses and relays located?

My lights wont come on ive changed fuses and bulbs what can problem be please n thanx


you may have a bad switch for the lights.if the fuses and the bulbs are good,you don`t say if your talking about the headlights tail lights,dash lights,signal lights brake lights,low beam lights high beam lights or both.i`m assuming headlights.if you have a daytime headlights,the relay in this car it could have gone bad as it is tied into the regular headlight system.

High beams work low beams do not


you don`t say if you have checked the fuses for the headlights.if the fuses are okay and you know that the low beam filaments are working.you may have to feed power and ground directly to the proper headlight prongs from the battery to make sure the bulbs are good.then it could be a relay for the low beams or a switch for the headlights.you don`t say if you have daytime running lights on this car as there is a module for this system that may be the problem for the now low beams.

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
