Toyota 4Runner Maintenance and Repair



  • As far as I know they turn on when the car is on but turn off when the car is off.. I would called the dealer and ask about. I don't seem to have that problem.

    Didn't see the previous message that triggered your response but I also have a 99 4Runner that had the same problem and I ended up getting a rebuilt start put in. It would away and there did seem to be a connection with weather and certainly the fact it was cold as it didn't seem to be a problem after it was running.

    I seemed to be able to save a lot of money in the repair by taking it directly to a starter rebuild company who charged a fraction of the cost of many of the other local repair shops.
    I didn't even bother talking to the dealership.

    I have an '04 SR5 V8 4WD. This past winter, when the temperatures dipped below -20 and -30, my low tire pressure monitor warning came on. Sure enough, the tire pressure was a bit low. I added the necessary air, but the warning light remained on until the ambient air temperature outside rose to above zero.

    The next time it dipped down to -30, the light came on, again, even though the tires were of the correct pressure. Once it warmed up to above freezing, the light went back off.

    I did not check the air temperature in the spare, but I doubt that it is monitored, is it? Anyone else have their tire pressure sensor malfunction, like this?

    The spare tire is monitored. I had the same issue until I checked my spare tire and found it to be low on air pressure. My 05 manual also states that the spare is monitored.

    We woke up yesterday (Sunday) morning to firemen putting out a fire under the hood of our 1995 Toyota 4runner. The neighbor who called 911 said it sounded like the 4Runner was trying to start itself. We had it parked at a park-n-ride for a week (no foul play suspected), I drove it home 8 miles and parked it on Friday and had not driven it since. It started raining on Friday afternoon and rained until Saturday afternoon. We had a new engine installed in 2003, and recently had the oil changed and new front brakes put in. I was in a minor fender bender in April '05, and the body shop said there was no damage to anything under the hood. Aside from a few minor oil leaks, the car was in excellent condition. What in the world could have happened that set our car on fire?

    That's rather disconcerting! In all likelihood an electrical wire had been damaged or was defective and shorted out possibly with assistance from the water.

    what is the purpose of the rear spoiler on the 4 runner? can it be removed without damaging the body/paint?
  • Idle becomes irratic when you put your foot on the brake. Idle is faster than it should be; cannot be adjusted below 1200 rpm. Idle can be "tapped" down to 1200, but then creeps up to 1500 or more.

    I have a 99 4runner limited also and around the end of last year the air control unit starting doing the same thing you describe. Did you find out what was wrong with the control unit? Did it have to be replaced? One auto place told me the unit itself was $700 if that is what needed to be replaced, but they couldn't tell by hooking it up to the machine. They told me I had to go to a Toyota dealership. Thank you.

    Rear spoiler is actually functional on the 4-Runner. Like many other "slab backed" vehicles, the suction of the vehicle going down the road often causes dirt, water, etc. to spray up on the back of the truck including the rear window. The spoiler draws air from over the top of the truck down over the rear window. It is EXTRMELY functional in keeping it clean compared to not having it. As for your second question, I'm sure you can remove it, but it is fastened with bolts so would need filler and paint once removed. Hope this helps.

    I have a 2004 4Runner, at 10,000miles both front "Sway bar Link pins" needed to be replaced. The dealer said that they have had problems with these parts. The symptoms were noise in the front end, slight instability on turns. The state inspection did not pick it up. I had to crawl under the vehicle and manually move each suspension part, from tie rods to the link pins. I immediately noticed that the right side was very loose and the left starting. I do no off road travel, and the vehicle is babied to the nth degree. The dealer replaced them easily under warranty. All 2004 owners check this out before the warranty runs out. No recalls yet from Toyota. Ford Explorer types had the same problem and recalled.

    Now you have my interest. Can you describe the noise? When did the noise happen? What kind of "instability" did you experience. As I've said, I just hear a metallic clank when I hit an especially abrupt bump or pot hole. I only hear it when the windows are down, and never when they are up. I have not experienced any "instability," although I'm not exactly sure what that means. I'd be curious if you could provide some additional information.

    Thanks in advance!

    Has anyone else had a problem with a small leak from the moonroof? I had brought in my 2003 4runner to my dealer and they advised me that the sunroof was designed to have drains to catch this leak. Should I be concerned??? since my warranty expires soon too. The rubber gasket surrounding the moonroof glass also appears to be "bubbling" up.... My dealer advised me that they would have to replace the entire sunroof assembly if I was to fix this...Any feedback appreciated...
  • I guess you should have kept it in the garage like me or at least oiled the rubber. After you leave it out in the sun, the rubber bubles up from the heat and sun damage; once it is to that point it is runined for life. I think your moonroof is toast now, you need to get a new one.

    Thanks for the info. I own a '95 4WD 4Runner and I imagine that it's the same headache (cuz it looks like it is). I shall attempt this on my own.

    I feel for you - vacuum leaks are SO hard to find. Rather than devices, check the vacuum hoses first, starting with the ones to the brake booster. I am assuming this is a 22R-E? The factory shop manual is very helpful for this type of problem - it has all the vacuum routings diagrammed. You need to meticulously check them all. In the end, I bet it is a hose rather than a vacuum control, but with the age of your Runner, it could be either. Good luck!

  • Please excuze my ignorance. If you have a sunroof on your 4R and you park outside (dont have a garage), then do you expect a leak in sunroof in three years.
    And to get a new rubber lining do you have to replace the whole sunroof unit?
  • Did you get an answer to your problem? I have a 2005 4runner and just purchased an 8 to 4 pin connector for the wiring harness for my trailer (trailer is brand new) but its not working....going to call toyota service when they open.....any suggestings?
  • I had this problem also, there "IS" a monitor on the spare, & this is usually what is causing this in cold weather....

    I wonder if it would be possible to order one without the spoiler. Every one I see in CA has it.
