#10 of 48 PLEASE HELP 1994 Toyota 4runner Electrical Problem. I need expertise pleas
Mar 07, 2009 (4:27 pm)
1994 Toyota 4runner. I connected a jumper battery in reverse polarity. Blew the 80 amp breaker and the fuel injection fuse. I replaced both and started the car, drove two blocks. Truck ran fine for first block as if there was no problems. Then it seemed to have a heavy electrical power shortage, dashboard indicators lit up and truck began to bog down towards a stall. I shut it down and parked it. I checked fuses under the dash and all seemed to be intact. To replace the fuel inj. 15 amp fuse, I pulled the hazard light fuse and used it. I was just going to drive to the parts store and buy the replacement fuse, but now the car sits and I don't want to try to run it until I know what else is wrong. CAN ANYONE HELP PLEASE. THOUGHTS, IDEAS, POSSIBILITIES.
THANK YOU. gary.schautgmail.com

You may have damaged your alternator and/or fried some electronics (e.g., ECU).

#12 of 48 Could This Be Electrical?
Mar 08, 2009 (5:23 pm)
I have a 1990 4Runner 3.0 V6 4WD. The car bogs out, makes a metal grinding sound, and loses power at 2000 rpm, it has minimal power until about 2600 rpm, once I pass that it is fine. Also in 4th and 5th gear, the pedal will be floored and I will have no power and be unable to pass 2000 rpm, the only way around this is too down shift and tach up the engine so that I will go into gear higher than 2600 rpm. I have recently replaced the max sensor, fuel filter/pump, all gaskets inside the block, and cat converter. I also have a clean K&N intake system, and I run high mileage synthetic blend valvoline oil. I don't know what else I can repair or replace to fix this and it's becoming very expensive. What can be causing this?
#13 of 48 Power front seat
Apr 10, 2009 (12:21 pm)
I have a '98 4runner with about 137,000 miles. Just recently the front passenger side power seat stopped working correctly. when you try to move the seat up or back only the right side of the seat moves. The left side remains still. I looked under the chair and found a single wire loose and reinserted the line. When I tried it after that the chair wouldn't move at. I pulled the line again and the right side would again move but the left remained in the same place. Any suggestions?
#14 of 48 truck died at highway cruise speed
Jul 20, 2009 (9:54 am)
1988 4-runner w/400k miles, was running great until it died suddenly on highway 2 days ago. A highway guy tested & said no spark. I've replaced both the Coil & the Ignition Module on advice from various people - it still cranks fine but no spark. I'd already checked fuses under hood, but have no diagram for under-dash breakers & relays. Can someone tell me what, if any, other fuses or electrical/electronic components are involved & likely to have failed suddenly, & where are they?
#15 of 48 Alternator up-grade QUESTION PLEASE READ AND HELP?
Jul 24, 2009 (11:56 am)
I'd like to thank you for taking the time read this email! I have a 1990 4-Runner V-6 4wheel drive 3.0 Liter engine. The stock 60 AMP alternator just went out and I had heard that you could upgrade to a higher alternator with an out put of 130 AMP. The 3.4 liter Toyota years 95 1/2 to 2004 but, that it must be the alternator that supports the tow-package? I had also heard that you may have to shim it to make it fit ? I have offroad lights that I plan on installing onto the 4-runner. Do you think that the switch from 60 AMP to 130 AMP will damage the electrical system in the 4-Runner?I can't find anyone that will give me any real information on the subject and I hope that you might have some answers to my questions? I really look forward to your reply and hope that life is treating you and your family GOOD

I appreciate the kind thought. If you live in the Tidewater area in VA, contact Browning's Alternator in Va.Beach. They know their stuff & are honest people, and should be able to help you. I had them rebuild the alternator in my '88 4Runner recently; it works great! I've also had them rebuild my 4Runner's heater-blower-motor, & previously they helped me with a problem on an '85 Vette. They can fix anything that's electric & spins in anything that moves on land or water.

I have a similar problem but in a gigantic proportion! 2000 4runner 6 cyl. My son installed a new stereo and it worked fine. Then we decided to pull the unit and install another and the next unit did not work at all. I checked all connections and everything was fine, but the 12v. constant line to the radio only was 8v. When I ran a new 12v the radio will work fine. In addition the car has the following: The clock is very dim and inside cabin light don't work. The parking lights on the front don't work. The bright lights don't work, but the brights light in flash mode. When you turn off the ignition then turn on the lights all the relays click,click,click but lights won't come on. blue Brights indicator light on instrument panel won't light.
I have spent two days following circuits on the thing and have the following: Constant voltage line to the radio tests at 8v. and drops to 2v. when any cabin lights or door switch goes on(lights don't come on)
I have checked all light switches and circuits for shorts.
Relays for running lights and brights ok.
Light control switch (low,flash,brights) ok.
#18 of 48 Headlamps not working properly
Dec 26, 2009 (8:07 am)
I have a 1999 Toyota 4Runner V6 Four Wheel drive with 140000K. While driving at night both headlamps turned off. I replaced the headlamp relay located in the engine bay, checked all the other fuses and unhooked the battery cables then reconnected. Now the headlamps are staying on when I turn the engine off and off when the engine is turned on. Can you please help me figure out what seems to be the issue. Thank you.

After three days of tracing circuits , I finally found the problem for this toyota's voltage problem. Under the hood where the mini fuses are located there was one fuse that was to the interior cabin lights as well as other things. this particular fuse had a led in it that lit when the interior lights were activated. This was the first fuse that I checked but it seemed to be working...ie the light lit when doors were opened. I pulled the fuse and checked for continuity and it ohmed out at no resistance on an ohm meter. later i found that the fuse was blown but the light allowed voltage into that part of the system flowing through the light itself,but the fuse was blown. later, when i put a volt meter on the fuse it was only putting 8 v. into that part of the circuit. When I changed to a new regular fuse without the fancy light built in, all voltage was restored and my multiple electrical problems were fixed. I don't know how this applies to your problem, but if you've got any of those mini-fuses with lights built in... get rid of them.
