Prius (2001-03) :: Headlights Coming On After Parking / Car Off
Dec 14, 2013
I sold my really nice Gen1 to a lady friend about 10 months ago. The few months I owned it, it was fairly trouble free and all I did was have the dealer replace the whole rack and pinion steering assembly on an old recall (no cost). Also change the OEM battery to the Yellow Top Optima.
Now the new owner has ask be to look into a problem she is having with the head lights coming on after she leaves the vehicle. It appears that this is just the head light and not the tail lights, so I would say that it has something to do with the daytime running lights part of the light control system.
She tells me that when she turns them off each time it happens, they come back on again when she closed the car. Since this was running the 12v battery down, she has been disconnecting the battery at the neg. terminal. So that has erased the OBD codes and history.
I now had her drive the car to my shop and I am waiting to see if the lights come on. This seem to start happening when our weather got cold, into the 20s and 30s. Not sure it hat is a factor. But today has been in the hi 40s and the lights have not come on since the car was turned off.
Now, I'm going to go out lock the car and turn the alarm system on to see if that has any effect.

I bought my Prius in November 2010. I replaced my headlights about three months ago when the right one went out. It went out again a few days ago. Then suddenly the diver side went out 2 days later. I also noticed that the right side parking light is out. The only lights that work are the high beams. I did check the fuses.
iPad ? HD ?

It seems about once a week the rubber cover that goes over the food pedal for the parking brake comes off. I've been careful to replace it correctly but it still keeps happening? Btw it's a 2010 v with atp ...

I have a 2008 prius that right after purchasing I found to have the condensation in the headlight problem, the dealer advised to replace the whole headlight assembly to avoid damage to the generator so I did. I did not have it done at the dealer due to the cost but at a prius certified mechanic at another location. Needless to say when he installed the headlight something was not done right and as a result the amber parking light is not coming on when the rest of the headlights are turned on.
I didn't notice this for a while and then when I did I neglected to get it fixed while under warranty for the labor. The strange thing is the light flashes when I lock and unlock my door, just won't come on with the other headlights. I tried replacing the bulb when I replaced my HID today but still the same result.

My dashboard light used to dim when I turned my headlights on (normal behavior). Now they go off altogether. Dangerous, n'est-ce pas? Is it a known issue with, for example, a fuse or relay?

This afternoon, when my wife went to start my 2001 prius, it was dead. I disconnected the 12V battery (relatively new) and checked the voltage. About 3 volts. So I put a charger on it and hoped. After about 12 hours it seemed to have enough charge to try it, and immediately the headlights turned on. I jumped in the car to turn off the headlights but they wouldn't turn off. I honestly don't know if the switch was in the on position to start with, but it's definitely in the off position now, and the lights are still on. What's going on here?

My (2001) headlights are always the dimmest of any car around me on the freeway. Is this a common issue with Prii? Yes, my lenses are clouded, but even when I clean them up, they are still dimmer (and yellower) than the cars around me.
Is this a possible indication of a problem with the electrical system?

I've noticed that if I have the dimmer wheel dialed up to maximum brightness before the detente that puts the mfd back to regular daytime brightness (hope this makes sense), in about the next minute and a half after I turn the headlights on, the mfd dims to roughly half the original brightness.

Ok. So i left work yesterday and realized that my low beams are both out. These are new bulbs so I checked the fuse under the engine hood. It had not broken. I grabbed my volt meter and got no current DC going into the fuse. Where the relay is located? This is for a 2001 prius.

I have a 2002 Prius with about 150,000 miles on it. A couple weeks ago, I noticed that the parking brake light on my instrument cluster didn't light up when I engaged it. Soon, all 10 bars on the fuel gauge started blinking. The seat belt reminder, open door warning, and headlight indicator lights aren't working, either. Any clues as to what could be causing all these malfunctions, or have I had more than one problem develop in close succession?

Out of the blue, our Headlights and Parking Lights would not switch on. Checked the fuses--OK. Tested the Relays--OK. Tried a used switch from my mechanic--no change. In the course of doing that, the Parking Lights came on and would not turn off. Tried disconnecting battery, locking/unlocking with the remote and starting it with the remote--no effect. Had to remove lightswitch 20A fuse to turn the P-lights off. Signals still work ok--with either switch. The car does have a HarmonKardon satellite radio which I've never used but have to turn off every time I start the car. I believe it has some sort of security system which annoyingly flashes a red button which sticks out of the dash.

I have a 2013 elantra limited with the tech package. Today I discovered that my parking lights or headlamps stay on after the car is turned off and the vehicle is armed. The interior blue lighting ( gear selection, push start ignition button, a/c selections, Eco button etc. ) stays on as well. I checked the fuses, but couldn't find anything that pertains to the parking lamps.
I usually run my lights in the drl or headlights position as I lost the auto feature when I installed my H.I.D's. And they usually shut off after a good 15 seconds.
I installed a powered compact subwoofer today and initially wired it to the same battery terminal as the H.I.D.'s but now have switched to another terminal.

I have a 2001 f150 supercrew 4x4 and my headlights will not turn on and my parking lights will not turn off. I have replaced my headlight and multifunction switches and it did not fix my issue. I have auto lights and fog lights. Does not matter what position i have the light switch in the headlights do not come on. I try to go from bright to dim still no headlights. I pull the ftp still no headlights and the only way to turn off my parking lights is to disconnect the battery. This is my only ride and its really aggravating not being able to drive at night.

I'm having trouble with the headlights on my 2003 Chevy Tracker. When it's light out, my headlights come on automatically when I release the parking brake, but turn off if I turn the switch that would normally turn them on. When it is dark out, or I drive under a bridge etc, they turn off and I can't manually turn them on. I can "flash" my headlights, but if I turn them on as if to leave them on, they don't turn on. This problem started about the same time that my AC blower stopped working, so I replaced the blower motor resistor and all fuses (I've heard that the blower motor resistor is also involved with the headlights). This fixed the AC, but had no effect on the headlights.
I can trick the lights into turning on at night only by shining a bright light directly on the sensor - they turn back off as soon as I remove the light. I took it to Pep Boys for a basic electrical diagnostic to see if I might be missing something silly, but once I described the problem they wouldn't even bother - told me to take it to the dealer and have the body regulator module reprogrammed.

I'm having problems with my front marker lights. The turn signals work but when I turn on the parking lights or headlights they don't work. They only work with the turn signals. And I can't get the front side marker lights to come on. I've tried everything...

Just picked up a 1999 F-150 XL, 4.2L V6, 5-Speed. Spent half the day rewiring the headlights back to factory as a previous owner did a bunch of wiring that made absolutely no sense. (Foglights or KC lights?). Anyway, works great with the exception that the headlights turn on when I turn the selector to just parking lights. I removed all but the factory wires under the hood. I haven't been behind the dash yet to check the headlight switch and I was hoping to avoid doing so. A fuse or relay that may be causing the issue? I don't have a service manual yet so I haven't been able to identify all the fuses under the hood.

Disconcerting noises from my engine that began suddenly around 198,000 miles.
Nobody listening seems to think it's bottom end, and I did check valve clearances and found them all to be on the tight side (ten within tolerance on the tight side, and six just-out-of-tolerance tight).
I also saw what looked like less oil on the #4 exhaust cam lobes and I'm wondering if there could be some kind of oil delivery issue. (#4 exhaust was also an area that had stuck out to the stethoscope before I took the cover off).
There's a dark brown varnish pretty much everywhere on the top deck (photo in other thread), pretty much as a thin coat that doesn't rub off easily, but I saw a few flat flakes coming off here and there, and wonder if that stuff might occlude an oil passage.
I've picked up a product called Auto-RX that I've never used before. From reading its patent I think there at least might be something to it (an ester of a fatty acid that's claimed to dissolve varnish and sludge without the other effects of more conventional solvents).

I have a 2003 Prius and replaced one of the failing batteries in my HV battery pack in hope that would fix the car. It now will not start, with the battery installed, and I have a p3030 code being thrown. Also, after sitting for a night, the main display goes black and has 'waves' in it when it does show. When I turn the switch on there's a clicking noise coming from the area around the battery.

Last week my ABS warning light came on. I took it to a mechanic (who I trust but is not a Prius-specific mechanic) who said warnings are coming up for the anti-lock accumulator and hydro boost motor. However, in July 2011 I had these both replaced. The work was done by a Toyota dealership. I ended up taking my car back 4 times after this work was completed as it kept having braking issues. They replaced the shim kit and bled the brakes. And eventually they replaced the master cylinder (this they did under warranty bc there was no way I was paying them any more money). At no point did they seem to understand what they were doing. (Along the way they broke my windshield and killed my battery.)
Finally by November 2011 my car was driving normal again. And then the warning light and high-pitched alarm went off again last week. I talked to Toyota Corporate who suggested I call the dealer to do the work since technically the accumulator and motor just ran out of their one year warranty. But this is the same dealer that didn't seem to know what they were doing last year.
