Toyota Sienna Maintenance and Repair (2003 earlier)

    As a general rule, you do have to slam the hatch pretty hard to make sure it's closed, unless you have a window, or door open. The car is very airtight. I'm not sure if that is related to your problem, it may be if you have a low battery. We have a 2000 XLE w/ 61,000 miles, and haven't experienced any problem like that. We did replace the original battery a few months ago.

    We figured it out!
    When we make a hard left turn the passenger door opens ever so slightly even when locked to make the stupid car computer think that the door is not fully shut or is being opened and in that brief instant, WALA! opens the locks. I can also do this by leaning into the door and sure enough it happens. Interestingly, we took iin for service and they even test-drove it and didn't discover it! I discovered it on the ride home after they thought we were mad! So at least we figured out the problem. Somehow, the door is not aligned perfectly with the locks/pins etc... My bro-in-law said it's a relatively easy fix.

    We have a 2002 Sienna LE Symphony with the passenger side power sliding door. I noticed the front edge of the power sliding door has a vertical rubber edge that fits nicely against the front passenger side door. After three years of ownership I noticed the drive side non-power sliding door does not have the black rubber edging. can other owners verify ?

    I only noticed this because of an annoying thumping noise we notice from the driver side sliding door and tried to see what is causing it.

    Any luck with this problem? I am also having this problem with my 2001 Sienna. It started about a year ago and we've been living with it because the light would stop blinking if you press the A/C button a few times. Now, the problem is persistent and will not go away. I took it in to the dealer today and of course the light did not blink. They could not find anything wrong! I hate when that happens.

    I'd be interested in hearing how anyone fixed this problem. I sure hope it's not the compressor because the dealer said it will cost around $1500 to replace!

    why not chk the drivers side door even if its not power the rubber edging should be the same, i think :D
  • lunarmistlunarmist Posts: 41
    Yes, I realize that. I'm hoping other owners can verify, either way, missing or normal.

    Also, is it normal that when we first drive off , cold, with our 2002 Sienna LE, the transmission has to first rev up to 3000 RPM before it will shift down ? once it shifts, its a smooth ride. we have 36, 400 miles.

    Our dog was in our van and chewed up all six shoulder/lap seat belts. Any ideas on where we can buy replacements at a reasonable price? Dealer's price is outrageous!!! $120-!60 each! Thanks!
  • deepandeepan Posts: 342
    thats normal. tranny will only shift properly once the engine has warmed up a bit. design intent. dont rev the engine too high within the first few minutes of startup.

    My seat belt warning light for the driver's seat comes on intermittently despite having the seat belt securely fastened. It appears to be random; I can see no explanation. I can get it to go out by fully extending , jerking, and disconnecting/reconnecting the belt. The light flashes, and I am worried that it might be signalling another problem.

    Does anyone have any ideas? Could the seat belt sensor be faulty. If so, how much does it cost to replace? Are there any safety concerns?

  • jprocjproc Posts: 135
    We had the exact same problem. After several weeks of this occuring-it stopped-now the light never flashes whether the seat belt is on or not.
  • deepandeepan Posts: 342
    i read in another forum that if you fully extend the belt and jiggle it a bit the issue witll be resolved. A low tech solution to a high tech van :D

    My dealer wanted $1425 to replace the compressor and clutch. Logically I could not see how the compressor could be bad since it worked properly when the light was not blinking.

    I took the van to an A/C specialist and they determined that it was just the compressor clutch that was bad. It was $300 to shim the clutch to get more life out of it or $600 to replace the clutch. I went with the replacement.

    The blinking light is telling you that the system thinks the compressor is not spinning at the speed that it thinks it should be spinning at (based on a RPM reading from the tach.) This is a fail-safe because if the compressor did lock up, the belt would break and therefore leave you stranded on the road. The A/C specialist was knowledgeable on the Toyota system and I am glad that I got a second opinion. While I am pro-dealer for the servicing of my Toyota and they would have fixed the van for $1425, I am glad that I didn't spend the extra $800+ that the dealer was suggesting I spend.

    Thx for the info.I actually was doing that and for a while it did fix the problem.However now the seatbelt light never comes on.I'll try extending the belt and see if that gets the light working again..
    I don't really care about the light working or not-issue I am concerned about is if the light malfunctioning would somehow effect the airbags from deploying in the event of an accident.

    I'm in a bind! I'm leaving in 2 days for a long family trip with wife and kids. For the past year, the rear and fwd lower power outlets have been inoperative on my 1998 Sienna. In testing the last remaining operating outlet (Upper fwd) with my digital voltmeter, I blew the fuse and now it doesn't work either. And now I can't find the fuses that control these 3 outlets. It sounded like a fuse blew under the dash, but I can't find anything that looks like a fuse. Does anyone know where the fuses are and what they look like? An email would be most appreciated.

    Many thanks for any help you can provide. A long trip without 12v power could be a very long trip with the teens!
  • deepandeepan Posts: 342
    i think the fuses are under the dash on the drivers side under a black cover. the main fuses are in the engine compartment behind the battery but i doubt they control the outlets. i have the manul at home and i will chk tonight, if i remember :D
  • akroegerakroeger Posts: 16
    Thanks. I'll look there for the one I blew. I checked that box before blowing the fuse when looking for the fuses for the other 2 inop outlets, but they were all good. Maybe when I blew the fuse on the last one, it was one located under the hood. I noticed when driving to work this AM that the power mirrors and clock were out, so they must be on the same fuse. Many thanks.
  • akroegerakroeger Posts: 16
    Eureka!! I found the fuses with the help of a coworker. They're located behind the coin drawer above the driver's left knee. One 15a fuse Power Outlets controls the fwd bottom and rear outlets. One 15a cig lighter controls the fwd top outlet (lighter), clock and electric side mirrors.
  • risaacsonrisaacson Posts: 1
    The power outlet fuses are located on the front panel left of the steering wheel down low. If I remember correctly it is not marked, you just have to pry it open to reveal the fuses for the power outlets. The same thing happened to me - had to call the service center who told me where they were. Enjoy your trip.

    My 2003 Sienna with 11000 miles has recently developed what sounded like a pre-ignition knock. I was using regular gas at the time so I switched to several tanks of preminum. The knock or what ever is still there. It only occurs as speeds below 30 MPH with very light throttle. It also doesn't occur all the time, and is too high a frequency to be a bearing knock. Can anyone shed any light on what this might be?

    I purchased a 2002 Sienna XLE with 35,000 miles right away noticed engine noise when first cranked and changing out of the first gear--mechanic said it was not a concern that all sienna vans of this year did this just let it warm up but this has not helped. Now at 42,000 it began not wanting to crank. I took to shop where I bought it and it did not fail the first few times they cranked it but on another try it did fail but they could not determine the problem so they sent it to the toyota dealer and he has not been able to diagnose the problem either. It will crank but RPM's drop to zero. It fails at different times of the day and the only thing that has been different was it has been raining all the week. Could it be a moisture problem? I purchased an extended warranty but they say the diagnosis is not covered by warranty so I will pay anywhere from 75 to 200 for this. They are keeping my van, but thank goodness the place I purchased it has given me a loaner vehicle.

    I am new to this forum and looking for help on how to connect the wiring harness for my Jayco popup camper. I have a 2002 Sienna Symphony. I installed the hitch already and now I am trying to find the plug on the Sienna for brake lites.
    My Jayco is 1998. I has both 6 pins male and female connectors. The male side connects to the Jayco. And the female is for the van. Does anyone know where I can tap/plug the female to? According to most people, they said the van should have a wiring harness already. I just have to plug it in. I have not been able to find it. I opened and looked both rear left and right lites, and the rear passenger side compartment. No luck.
    I found a set of wiring run along back to both rear lites. Does anyone know where I can find the conduit? Or I have to cut the wire and tap the harness? Do you know where I can get the schematic for Sienna?
    The dealerships gave me a run around for quite sometime.
    Any help will be greatly appreciated.

    My 2003 Sienna has the same knocking noise. It only last for about 3-5seconds. It only has 19000 Km. The noise only happened at the first time start in the morning. The dealer has kept my van for a week now. They don't have the clue about it. But they think it is an engine abnormal noise. I have already complained it to Toyota customer service office. I suggested you do the same. I will keep you informed when I got back from the dealer.
  • deepandeepan Posts: 342
    cold metal without lubrication tends to make noise. thats what is happening when you start the vehicle in the morning. nothing to worry.

    We just spent $3300 to have our transmission replaced on our '98 Sienna

    Wow, that's as much as many charge for an engine.
  • don105 is your engine cold or hot when this occurs?
  • freebirdfreebird Posts: 77
    That is about what I have heard for a dealer replacement cost.

    How many miles were on the van? What type of maintenance interval did you follow up to the failure? What type of failure did the transmission suffer?
  • deepandeepan Posts: 342
    i hope it was covered under the extetnded warranty.
  • giraffe1giraffe1 Posts: 2
    Discovered today the car was a manufacturers buy back in NY then resold to me. What options do I have in Georgia?
  • don105don105 Posts: 6
    Engine is fully warmed up. The noise doesn't occur when engine is cold.
