Toyota Avalon Electrical Problems

    On the passenger side edge of the lens, in the very center, there is a small indentation for a flat bladed screwdriver to be partially inserted, insert the screwdriver into the slot and move the handle toward the passenger side window and the lens should pop off easily, there are 2 tabs on the opposite side that secure that edge in. Hope this helps.

    I have the exact same problem as in message #83. Does anyone know what the cause actually turned out to be? 98 Avalon 35k. Dealer appt 7/24/03! Can I fix it myself?

    96 avalon hazard light inside the switch (interior) is burnt. Anyone know the procedure. does the front panel come off or can the switch itself gently taken out. thanks
  • I too have the exact same problem both of you were having (MSG #83 and #212). Would really appreciate it if anyone could post the cause of problem and the $$ to get it fixed. I have a service appt in a few days.

    Thanks in advance.
  • '96 Avy, less than 70k miles..woke up and wouldn't turn over. Charged battery for 2 hr til it turned over and then started driving around died and pushed it home!
    This a.m. clicks when trying to start and won't hold a charge...battery's not that old and I'm afraid to put it on the road in case it dies again. Battery? Relays? Our toyota dealer has made a fortune on this car -- suspension/struts already.

    Sounds like my older cars behaved when the Altenator went out. Can you still test the altenators by cranking on a charged batt then disconnecting the battery to see if runs?
  • Age of the battery means nothing. I've had virtually new batteries fail and I've had '48 month' batteries last twice that long. My 96's OE battery lasted 7 years.

    If you have a volt meter available you can check to see if the alternator is charging the battery. Start the car (charge the battery or jump start) and check the voltage across the battery. It will be over 13 is the alternator is charging the battery.

    If you check the battery before starting the car it should read 12 or just above. Less means you have a battery problem. If you can start the car without a jump look at the voltmeter while the car is cranking. If the voltage drops close to 10 or below 10 you have a bad cell in the battery.

    If the battery is low on water cells fail sooner than when the water level is correct. The green eye on battery top checks only one cell. There are 6, so any of the others could be bad and the 'eye' would indicate a good battery.
  • NO! Don't test the alternator by disconnecting the battery cable while the engine is running. BADDDDD Idea!

    Is there a short explanation as to why disconnecting the battery while a car is running is now a bad idea, or has it always been a bad I idea, and I never knew it. (Sincere question) Thanks,
  • Destroys the diodes. They generally do not like current going in more than one direction. They are a one-way street.

    Right on - DO NOT RUN ENGINE WITHOUT THE BATTERY. It is in the manual. You will destroy your very expensive electronics. Call AAA if you are a member and they'll test it, or take the car to a Walmart service center if it runs, and they will run a stress test on the battery and the alternator at no charge. If it is the battery they have pretty good deals on replacements. Our Sienna battery died after 18 months, but it was cheaper to buy one from Walmart than get it replaced under warranty because of the "pro-rated" cost.

    First ,thanks! John609.

    Another question please anyone knew it give me some helpful suggestions.

    Just bought a 1996 Avalon XL.
    The rear tail light warning often lights on after driving for a few minutes. Sometimes it doesn't light at all. It looks strange. I checked the car all around it. I found the front parking light is burnt out then I replaced it. It still lights on (rear tail warning). So I changed another front parking light (it almost burnt out). I think it should be normal again but never. I checked the rear tail light working normal. The backup lights normal, the turn signals normal, the license plate lights normal.... Anyone has ever met this situation before? Thanks!

    i had an older camry that had warning lights as well. Everytime it rained or moisture in the air the warning light on the dash would come up. All exterior bulbs were fine. After they dried the warning light would go off. Happened for yrs on the car. Water didnt collect in the bulb holders/compartment

    The rear tail light indicator on my 97 had been lit up for much of the eight years I've had the car. I've never been able to identify the problem myself (should be simple, right?) Recently a dealer service center finally fixed the problem for me, and they mentioned to me that one of the tail/brake lights (I unfortunately don't know which one) is "multi-element" (what that means I'm not sure), and for the nonexpert like me it would be difficult to identify that one of the elements was not operational (hence the indicator light comes on). Anyway they fixed it for less than $10, if I recall. I can't tell you how much better I feel without that rear tail light indicator light constantly annoying me. Good luck.
  • I am having a similar problem with by 97 Avalon XLS. Bought the car in Virginia in 99 with 26000 miles. Have been living in Maine since 2000. In November of this year, '04, the car wouldn't start. Battery was low on fluids, added fluids, but didn't help. Decided that after at least 7 yrs, I needed a new battery. Bought one off the shelf at local Napa store in late afternoon. Car started right up. Next morning, nothing. Recharged the battery--on the assumption that it had been sitting on shelf for long time and didn't have much of a charge. Car started. Just to be on the safe side, I decided to take car to dealership. Couldn't get an appointment for several days, As I used the car over the 5 day interim period, I kept taking off one of the battery leads as I assumed there was a discharge occurring. Under that practice, car started all the time. When Dealership checked the battery,they could not find any problems. According to their report,"... battery/charging system, battery test good. Has a 19 milliamp draw which is (sic) exceptable. Charging voltage is 13.2-14.5 volts. It cost me $68. They said if it happens again, they would want to keep it for a day or two.


    So, with that diagnosis, I left the battery leads on all the time. For the better part of a month, no problems. Until yesterday. Didn't use the car for two days. Temps have been in low 20s in garage. Battery totally drained. Re charged the battery, car started right up.


    I normally leave the lights and the radio in the on position when I turn the motor off. Under those "on" conditions, when I recharge the battery and replace the leads, the headlights come on. And this is without the key in the ignition and turned on. Then when I start the motor, the radio switches to the CD player. Does that indicate anything other than defaults?


    My question. Where do I go from here? What can I expect from the dealership? Should I take the car say to a AAA repair shop first? Has this been a common problem with Avalons of the 1997 period?

      About 2 weeks ago, my 96 Avalon had have the rear warning light on when I drive for appr. 45 min or so, but it is randomly, I check all light when the warning light is on, all light bulb is good. So do you already fixed the problem? I appreciate if you can tell me the solution, or Anyone who know the answer? Thanks!
  • Had something similar happen to my 96 a few years ago. All the bulbs worked when I checked, but still got an occasional warning. Changed all the tail light bulbs, including the center brake light, and the problem went away.

          Have been busy these days. A little late to reply you.

          For my case, it was all fixed after I changed the parking lights. (next to head lights)

          It's number is 168 and you can buy a pair in stores with less than 2 or 3 dollars. Do it as the owner's manual then your problem might be fixed.

           The previous parking lights still working but dimming. I changed one but still warning. So I changed the 2nd one but still warning. I give up that day. It is wonderful when I get up the next morning. It doesn't show any warning at all. It never bug me until now.

             I don't know if it works for you. It looks like someone else fix the problem by replacing the rear lights. Anyway, good luck to you!
