Can you see the smoke colored sensor near the windshield? I've had one break and fall down which caused this exact problem. If you can see it, pull the plastic trim piece off, make sure the connections are actually connected, have seen these come unhooked.

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

SOURCE: 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?

Was the dodge caravan 2002 equipped with daytime running lights?


You can tell by looking at the headlight switch. Without daytime running lights, the switch only has 3 positions, "Off","park" and "headlights" with daytime there is a fourth position to use or not to use the daytime lights.

Low beams/ day lights not working


If everything else checks out as you say then there may be a bad/loose connection somewhere in the wiring and would have to be traced from switch to both headlamps if your daytime running lights and headlights (with switch turned on) works intermittently. and/or your switch itself may be starting to go bad (bad contact, etc.) and would need to be replaced. hope this helps

I have a 96 Yukon just last night the daytime lights went out both of them can you help me please..Barry


Im not sure I am following you. When it gets dark enough the "daytime" running lights should go off and the headlights and tail lights should come on for night time driving. The head light switch must be set in the "auto" position.
Regards.

2002grand am daytime running lights


99 - 04 grand am.

I had the "service vehicle soon" light come twice with in 1 year. First the heald light bulbs were gone. Replaced the head light bulbs and after 2 starts the "service vehicle soon" light was gone.

The second time the DRL - #194 amber bulbs were gone. Replaced these and the "service vehicle soon" light was gone after 2 starts. The DRLs are housed in the headlamp housing, the tiny bulbs beside the head light.
