Toyota Camry Fuse and Electrical Questions



  • kiawahkiawah Posts: 3,666
    When you say they quit working, do you mean that the outside lights light up but don't flash??? or that the outside lights don't light up by either the hazard or turn signal switch?

    There are two fuses as part of this circuitry, the 7.5A Turn, and the 10 A Flasher. Both of those feed the hazard warning switch. After the hazard warning switch, power is fed to the Flasher. The flasher then feeds the turn signal switch.

    So problem could be the fuses, the hazard switch, or the flasher.

    The flasher is down under the dash, on the left. It's NOT in the fuse box under the dash by your left knee.
  • They don't light up or flash. The hazard doesn't work either. I presume it's the same lights, right?

    So how how I get to the flasher on the left? Should I remove the panel under there?

    Good luck.
  • Great! Thanks! I'll try it! So, just to make get to it...I should remove the panel under the steering column? Or how do I get to this area?

    Let you know how it goes.

  • Did it! WooHoo!!
    Thanks a million for all your help!!! :)
  • I have been searching for an answer to a perplexing car problem(s) with my '93 Camry.

    1. My headlights started flickering on and off, eventually stopped working. When he left turn signal is used they turn on - a right signal turns them on. Either way they don't stay on for long.

    2. The brights work but only if I hold the lever down; leaving them on they work the same as the regular lights.

    3. My entire car shut down while I was driving; I couldn't turn it back on or shift into neutral so it could be pushed into a local gas station. Then it turned back on and I'm not sure why.

    Please help me figure out what's wrong - I don't know if my fuses are overheating or relays or something. I'd like to figure it out so I can fix it at home - anything helps. Thanks!!

    Excellent....congrats...nice job!

    Is this a USA vehicle, or Canadian vehicle? Electrically they are different in this headlight area.

    Do I understand your high beam situation correctly. When you hit the 'flash' function the high beams will come on, but normally they won't stay in the on position.

    When you turn your headlights on and get them you have taillights at the same time that the headlights are on?
  • kiawahkiawah Posts: 3,666
    You haven't responded and I'll be out for a number of days, so let me give you some additional info.

    If I assume that you are a USA vehicle and not Canada, and assume that your taillights do work when your lights are on, and assume that you are able to flash your high beams, then your problem would be either your light control switch is bad, or the integration relay.

    There are additional tests that should be performed with a meter to definitively prove before you tear into your steering wheel.
  • I apologize - yes, I believe that is true. The taillights work but the headlights don't.

    Please let me know some of the tests/how to run them when you get a chance. Thank you!
  • What is the best test to run on these?
  • kiawahkiawah Posts: 3,666
    The link I posted is a document, which has the test to run on each pin setting with the expected results. These can be done with a digital volt/ohm meter.

    If all of this is greek to you and/or you haven't worked on vehicles before, you should consider taking it to a repair shop. You have a good idea of what the problem is, and can get their estimates up front as to what they would charge to do the repair.
  • Thanks! Do you mind emailing the pictures to me, they are rather small when I try to download them from the page.

  • for some strange reason my park lights stopped working...both at the same time. Is there a fuse that might of caused this issue and if so where is the located because i dont have a fuse diagram in my car..thanks :cry:
  • blu28blu28 Posts: 1
    I have exactly the same problem as salsaqueen on exactly the same car. Unfortunately, I can't figure out where the flasher is based on the three jpegs you posted. Do you have a larger version available?
  • kiawahkiawah Posts: 3,666
    Open the 'flasher 1', and zoom in with your browser if you need to the middle of the picture. It is marked where the flasher is in the junction box.

    Find the junction box in your car that is shaped like the one in the picture, positioned the way it is, in the area where that junction box is. Once you have located the junction box, then look at your junction box closely where the arrow is pointing to the flasher.

    when you say 'both', do you mean all 'four' of the corners don't have any parking lights?

    Is your license plate light out, as well?
  • front park lights are the issue i dont have any at all....but the light above the back plate works fine...i just figured it was a fuse and dont know which one to change out thanks
  • kiawahkiawah Posts: 3,666
    If you are saying that your symptoms are:
    - the front parking lights DON'T work
    - the rear parking lights and the license plate DOES work.....

    then your problem has to be either your front bulbs are burnt out or the wiring to the bulb has a problem. They are all fed from the same circuit, and there is no fuse that feeds the front parking lights separately.

    Pull the front bulbs, check for a bad filament and or connection in the socket, use a ohmmeter if you need to verify that the bulb is good or bad, and a voltmeter if necessary to check that you have voltage in the socket.
  • thank you! we will check that in the morning after it stops snowing...thanks again

    Both reverse lights do not light.
    Both tail running lights do not light.
    License plate illumination does not light.

    The dash "tail light out" indicator lamp is OFF when the headlight switch is off, and ON when the switch is ON(both parking and headlight on) and also ON when the auto headlight sensor turns on the headlights.

    I have checked the following fuses which were good:
    TAIL (Instrument Panel JB#1)
    GAUGE (Instrument Panel JB#1)

    I have visually inspected the harnessing in the trunk (where the high stress area would be) as well as the harnessing to the light failure sensor and didn't see anything that got my attention.

    Additionally, the first time I noticed any of this was when the check engine light came on with code P1780 (Park/Neutral Position Switch Malfunction ) and was accompanied by the reverse indicator on the dash being illuminated at the same time as the drive indicator light (or park etc). The check engine light went off on its own and has not come back on since, and the transmission dash indicators are working correctly again as well.

    Last but not least, this car has an addon remote start and keyless entry. Dont know if thats playing a role.

    Do your brake lights work, or not?
  • teddawteddaw Posts: 6
    The brake lights work fine. Just pulled two of the relays... trying to check them now! Pulled and checked two relays on the back of the Instrument Panel J/B (the one on the passenger side as well as the middle relay-- Part #s VFM-11F41-ZO5) and with 12V on the coils the contacts closed.
  • kiawahkiawah Posts: 3,666
    It appears you've got a couple different problems, which is making me wonder what the common thread might be.

    The simplest of the circuits is the backup lights, and I think we should start there to figure this out. The power to this circuit comes from the ignition switch, thru the 10A gauge fuse (which I believe is good because that gauge fuse also feeds the indicator light that is telling you that your tail lights are out), thru the backup switch, and then to the 2 backup lights to ground. Can you get a digital voltmeter, and meter the voltage on the 10A gauge fuse, to verify that it is sitting at 13-14 volts. If that is good as I suspect it is, then measure the voltage on the backup switch. If you have voltage on both legs of that switch, then go to the backup lights and verify that you have voltage on power feed to the backup lights.

    I had initially suspected the taillight relay for the plate lights (which still might be involved as another problem), but let's figure out the simpler backup light circuit first.

    If you are able to check relays, then check the tail relay. There are three relays in a row on the otherside of the junction block where the tail fuse is, which I think you've found. If you are looking at the block staring at the relay side, the right hand one is the tailrelay. It's by a small yellow connector, and the tailrelay has a different connector plug immediately above it. This tailrelay isn't related to the backup light problem, I only offer it now since you are already checking relays.

    Kiawah.. thanks so much for your time!

    All three relays have now been checked (on a bench) and seem to be functioning properly. I also checked Gauge with the ignition on and there was battery voltage on both sides of the fuse. Can you give me a bit more info as to where the backup switch is? Whats the easiest way to access it?
  • kiawahkiawah Posts: 3,666
    Don't know whether you have an automatic or manual transmission, but the switch is on the transmission. WIth the hood open, stand in the middle of the car facing the engine, hold out your right hand, and drop it down toward the transmission. That's the area the switch is in, which detects when the transmission is in Reverse.
  • teddawteddaw Posts: 6
    I have the automatic.. I have found the park/neutral position switch... and what I think is the vehicle speed sensor. But no joy on the other switch. Its getting dark and my lighting is awful. I think I'll knock off and try some more tomorrow!
  • kiawahkiawah Posts: 3,666
    That's the switch, it will be closed when the gearshift is in Reverse. Check the voltage on the pins. One pin should be hot (14V) when the ignition is ON, the other side should be hot only when transmission is also in reverse (while the ignition is in ON position). Shorting the switch pins should give voltage to the rear lights, and they should light up.
