Toyota 4Runner Maintenance and Repair

    Second possible answer.
     Your 4Rrunner has an inordinate amount of gravitons (from the particle theory of gravity waves). From Einstein's general theory of relativity, gravity distorts electro-optical waves. Those excess gravitons are distorting the electrical energy going to your mirror.

    Either that, or you dealer did it wrong

    Is is possible to simply purchase an autodimming rear view mirror, install it on the windshield (in a 4Runner without a factory autodimming rear-view mirror)and have it be functional? Without having to remove the windshield or make any other major modifications?

    Yes you can install a auto-dimming mirror. You will have to do some wiring though. I think I read you need to tap into a wire down near your driver's side door sill. Not too complicated but it is not plug-n-play.
  • Thank you my2cents. I received the new relay, and followed your instructions, and it worked great!! I feel like my truck is worth million bucks more!

    I have just had my master cylinder replaced on my 2004 4 runner. I reported the problem after 1500 to my dealer and they said it was normal. I felt this couldn't be the case and went back to them when I discovered I had the sulfer smell, and complained again. This time I brought with the information from this forum. The service writer had the mechanic drive the truck and he confirmed a problem. They called Toyota in California, who said they have no documentation on this problem. This time I got the dealer to read the information posted on this site and they replaced the master cylinder. My thanks to everyone who posted the problem and solution. It clearly made the difference.

    Just wanted to toss in my report of the driver's seat rattle in my 2004. It has less than 4K miles on it, and I would say the driver's seat has as much as a quarter inch of play in it.

    Sure seems to me that it is the height mechanism or something other than its mount to the rails. That seems secure to me.

    I find it quite irritating and distracting to have the seat "knock" every time I turn or brake or accelerate.

    I am also disappointed that the most expesive vehicle I have ever purchased has the worst seat. And that includes a 1968 Dodge Polara for goodness' sake!

    Shame on Toyota for not fixing it by now.

    Has anyone experienced load noise and jerky response when using the DAC. On a steep hill in low 4x4 DAC, my truck makes alot of noise, even worse than ABS brakes, and is very jerky. At times it pulls to one side even on a paved steep downhill road. I am trying to determine if this is normal. When I received the truck it had to be serviced because the low 4x4 was not connected properly. I would appreciate any feedback from anyone who has used the DAC on a 4x4. My local dealer does not service many 4-Runners so I want to have my act together when I take it in. Thanks in advance.

    I currently have a 2004 Sport 4x4 V8 that includes the factory auto-dimming mirrors. I have direct experience in special ordering one with the factory auto dimming mirrors.

    My factory installed mirror version does not have the problems that you are reporting. I suspect it is an installation problem, most likely a wiring problem.

    it does make a lot of noise. this is normal. it's modulating wheel spin, brakes, and gearing all at once. just something to get used to. you really won't need it except for extreme downhill offroad cases.

    I bought a new 2004 4Runner (Limited V6 4WD) last week. Whenever I start the car, water or some other clear liquid leaks profusely from under the engine on the passenger side.

    The leaking is so profuse that it's as if someone opened a tap of water under the hood. I know that when air conditioner is used there can be some condensation but the amount I see in this 4Runner seems abnormal to me. It leaves a trail behind wherever I go.

    Any ideas on what could be possibly wrong?

    Thanks a lot!

    My 2004 4Runner limited leans to the left about a half inch. The District Service Manager in the southeast says that this is normal and nothing needs to be corrected. Does anyone else have a similar situation?

    What will the effect be on my 2000 4runner for using 85-86 octane gasoline. I seem to have an engine rattle everytime I go up a hill or start off from the stop light. Any help on fixing the problem? I use arco while i'm home. 87 octane.

    The 'leak' may just be from the A/C. If so, it is no problem. Mine drips a bit, but I live in a low humidity area. Try running without the A/C and see if it still drips. Also, rub your finger in the fluid and smell it. If there is any gas or oil smell, take it to the dealer.
  • tangmantangman Posts: 127
    If I ignore the noise, should it slow down smoothly or very jerky. By that I mean, it comes almost to a stop, then releases and goes fairly fast until it engages again. I simply do not know what is normal. I thought that it might make noise but slow down smoothly, not go between 1 and 5 mph intermittenly.

    If it leaks immediately (within 15 seconds after starting), it most likely is not the air conditioning. It could be a disconnected, wiper/washer hose. If it leaks after running a short time,it is most likely the airconditioning. The airconditioning some times is turned on automatically under certain conditions. Per another post, check the fluid to confirm that it is water. When you say start, has the truck set not being run for at least 4 hours. If you restart when hot, the air conditioning may drip considerable water especially in humid environment. This is based on my experiences, however, keep in mind I am not an expert.

    hello.... I'm in the market for a mid-size SUV used for delivering fragile items (wedding cakes, individual boxed desserts, etc). The second row seats fold flat, which is what I very much need in an SUV; but the ledge that fits over the wheelwell in the cargo area is a problem. Has anyone successfully removed it? I can see going over a bump with a wedding cake in the cargo area... and oops - there goes the top of the cake! I've had to rule out Pilot, Highlander, MDX, BMW, Volvo, Explorer, etc because of the second row seat (not folding completely flat) and I refuse to buy another Grand Cherokee. So any ideas are appreciated! Thanks, Jeanne

    jholt28 do a search for messages that start at message 8514 and run through 8536 for reference to leaning 2003 4Runners in the main 4Runner Forum. Message 8516 is the first set of measurements(mine) followed by message 8520 for another members #'s. There has been no change in my lean still 1/4" lower on the driver's side when it has sat for awhile but the lean disappears after the 4Runner has been driven. Strange but true I've measured it immediately after and the 1/4" difference from side to side in the front is gone. I have read on other Toyota forums about this same problem and even on some Lexus forums in which GX 470 owners have noticed the same issue.

    If you mean the double deck cargo system then yes, the cargo deck can be removed easily. But if you are just buying it now, just don't get that option.

    In reply to post #522. I think I know what you mean by the odor. I have a 2001 Lexus IS300. It does the same "odor" thing everytime I depress the gas panel all the way to the floor for sudden rev up the engine. Does it smell like rodden egg? I don't know what is causing the rodden egg smell, but I turn the air circulator to RECYCLE instead of FRESH. The smell disappeared. It seems like the smell comes from the engine compartment/exhaust. Try to switch it to RECYCLE the cabin air to see if it helps.

    If the condensation smells that putrid there must be some awful gunk inside the ducts. It happens at no specific interval. You go for a couple days with nothing then yesterday we were out for 40 minutes and got hit 3 times. Each episode lasts about 30 seconds to a couple minutes. My wife said this morning it did it when she was on her way to work and it seems to be happening more frequently and longer. It almost seems to me as if something is leaking into the one of the ducts in the back of the engine compartment. We are bringing it back in to the dealer tomorrow. I don't have very high expectations but I'll let you know what happens.

    I just test drove 2004 4runner Sport & SR5 v6 models. The trucks were brand new, with less than 10mi. I was diappointed with the amount of drive vibration occuring after 60mph. Most people claim that the 4runner is a very smooth ride. I noticed much more vibration when driving in 2WD vs 4WD modes. I test drove other SUV's like Ford Escape, and noticed the other test drives were very smooth rides. Can anyone explain the 4runner vibration?
