Question about 2003 Toyota Corolla

Daytime Running lights run the battery dead

The car is turned off, in my driveway over night, and the daytime running lights just turn on which runs the battery dead. It usually happens when it is less than 25 degrees outside. I've taken it to the dealership and after 2 hours they still could not figure it out. I really don't want to pull the fuse every night for this problem.

    I have the same problem. At night, the lights will not be on, and in the morning they will somehow come back on. I have already taken to the dealer and they've not been able to fix. The best part was when they announced it 'fixed', then we left it there overnight, picked it up, and the problem must have happened again, because it didn't start again the next morning! Look on their faces was priceless.

    Anyone have a solution? Please? It's really annoying to have to guess when I need to give my wife a jump in the morning, as it only seems to happen a couple times a week, not every day.

    We have the exact same problem: running lights turn on by themselves when it is cold and run the battery down.

    I have the same problem on my 86 4-runner (forunner). Light switch (on steering column) is off, and key is out of the ignition (with car completely off) but the regular parking lights stay on and will drain the battery. I am tired of having to disconnect the positive cable from the battery every time I go somewhere.

    This started happening last week when it was very cold and I drove in a snow storm. I suppose it is possible water is shorting out something, but I don't think so see as I have drove through many storms this year and nothing like this happened.

    Do you recommend replacing the whole headlight switch in the steering column?

The Toyota Service Bulletin is 059633, dated March 13, 2003. My 2003 Corolla has the same problem. When the lights were on this morning after a very cold night, I jiggled the headlamp switch and sure enough, the headlights turned on and off. I found that the lights can be kept off if the switch is pushed forward and left in the "high beam" position when the car is off and the weather is expected to be cold. This is easier than pulling the fuse every time, until the switch can be replaced. It worked for me. Hope this helps.

I had the same problem but found a solution. Turn the bright lights on before turning the car off and leave the bright/dim light leaver in the down (bright) position. For some reason this stops the lights from coming on when the temp drops below the 20 something point. Has worked for me each time this winter including today when the temp stayed below 27 degrees outside.

1998 Lumina lights don't work at night!The lights work during the day but not at night. Does anyone know how to fix it?

Theres a sensor in the middle of the dash by the front windshield that detects sunlight and triggers the automatic headlights. The main headlights and daytime running lights might be on a different circuit, in which case they daytime running lamps would turn off at night and the main headlights would turn on, indicating the main headlights arent working and the daytime running lamps are working as intended.

I would check all the fuses related to headlights, check the bulbs and check the switch, then last the light sensor on the dash.

Fitted hid headlights now driving lights dont work

The problem with HID lights is that they require 12 volts or more to work. Daytime running lights on require 6-9 volts from the module. So when the original lights are replaced, the daytime running lights will not supply enough voltage to the HID ballasts to turn them on. The result? No Daytime Running lights. Another alternative is to purchase LED strips and place them around your headlights with a fused accessory power from the ignition switch. When the car is on the strips light up and you have Daytime Running Lights!

All exterior lights are on when engine is started and wont turn off until engine is off, could it be the switch itself?

Is this happening all the time or just at night? The car is equipped with automatic daytime running lights which automatically turns on the full lighting system at dusk and off at dawn or other lowered daylight situations. Do you have something on the dashboard covering the daytime running light sensor? Is the headlight switch turned to the off position?

Daytime running lights

Just reverse the polarity of the wires (plug them in backwards) on the battery and without turning the key or anything, turn the lights on. This will cause the DRL and ALC feature to stop working. Then return the cables to to the proper polarities and voila, there you have it. Now you have total control over your headlights, day or night. I did this to my car because i put HID bulbs in and they work perfectly. 7 months and no problems with the lights or the service light coming on soon.

Daytime running lights and blinkers do not work

the lights are controlled by a module, it is the DRL module, replace it. also try this
On the inside of the car next to the light switch there is your dome light button. GM made it to where you could turn off the daytime running lights by pushing it three times in and out. Turn the vehicle on then do this. Your daytime running lights should work after this.

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.
