08 tail light lens by badgermom
Jun 17, 2008 (6:16 pm)
Reply
Hi, I have a question about replacing the lens on my 08 Sienna. I had a run in with my garbage can backing out of my driveway today and broke the tail light lens on the passenger side. My husband is going to kill me when he finds out as we have only had our NEW car for 2 weeks. I called the dealership and they want to charge me $256.00 to replace the entire tail light. Since I only need the plastic lens I was wondering if I could just order that by itself. I can only find 07 replacement lens. Does anyone know if that is compatible with the 08 models. Thanks for the help.

Bummer.
 
I doubt it changed, but does the dealer have any used 07s that you can compare against?

Here's my two cents...call your dealer and speak to the parts department. Ask them to check the part number for a 2007 Sienna, as well as for the 2008. If they have the same part number, the 2007 tail light will fit your 2008 Sienna. Next, I would highly suggest checking Ebay for a replacement tail light, or your local auto junk yard. Unfortunately, late model vehicles get totaled too, and they might have a tail light fr you, or the means to get one. Lastly, you or someone mechanically inclined will be able to swap out these tail lights. The tail light is held in place with two pins on the leading edge of the tail light (on the side of the van), and with two screws that are hidden by the rear hatch. First remove these two screws that are exposed when you open the hatch. Then gently pry the leading edge of the tail light away from the van. You will see these "pins" and where they are located on the replacement tail light, before removing your damaged one. Just be sure not to damage the paint when doing so. I placed a rag against the van before prying the tail light loose with a flathead screw driver. Then with the tail light in your hand, disconnect the wiring harness to the tail light. There will be a single secure clip that needs to be pushed down with your finger for the connection to come apart. Go to the following website and click on "instruction sheet". Once the instruction sheet opens, you will see pictures of the tail light and how they are removed.

I did end up bidding on an ebay auction and got just a replacement lens for $22 (plus 18 for shipping). I appreciate your help and I copied your instructions down for my husband so he can change it out. Thanks so much.

2000 Sienna lost electrical function to door locks/alarm and dome lights by 01miami

Other electrical work is working
 
Electric door locks do not work and rear tailgate door cannot be opened. Dome lights are out but all other electrical functions are working. I changed the fuses for the door and dome lights even though the weren't blown. "Check" light came on when this started.
Is there a common wiring for these 2 processes?
thanks

It could be that the dealer service personel are not as "brave" as you regarding how fast they will enter a somewhat tight (my assumption) turn...45-48 mph. You may be encountering the rollover prevention aspects of the Sienna's VSC/Trac "nanny".
 
But you seem to be describing a circumstance wherein a small level of "plowing"/understearing is almost a given. Braking and turning (tightly..??) at a fairly high speed. Remember that your front brakes will be responsible for 70-80% of the braking effort and "here" you have the front wheels turned at an angle, thereby maybe asking of the front tires' traction coefficient a bit more than they have to "give".
 
So of course the VSC will sometimes activate in that circumstance.
 
Throw in a bit of slipperiness to the roadbed and VSC will ALWAYS activate.
 
The VSC in my '01 RX300 seems to be a bit more prone to activate VSC in "your" circumstance when there is also a slight, but definite, rise in the roadbed as I turn.
 
Are you, by any chance, applying the brakes because you recognize your entry speed into the (tight) turn is too high...?? In that case the VSC is simply being helpful.

Having exact same problem on our 2007 Sienna LE.
Wondering if you've made any progress in getting it fixed.
Thanks.

Sorry we have finally given up. After numerous trips to the dealership and they could not "reproduce" the problem the only thing they could tell us was that they would note it in our records. If you find someone that can give you an answer please let me know. My husband has made a video on his camera phone showing the dashboard lights but the mechanics still have no explaination. Good luck!

I had similar problem. Driver window on 2000 Sienna--intermittent stopping. Use suggestion at your own risk. I bought spray can of electrical contacts cleaner--check trade stores that cater to electronics technicians. I removed window control assembly and (can't remember exactly how far) disassembled until I could see actual contacts. Sprayed clean & reassembled. Be really careful with dis- & reassembly. Don't try unless you're willing to replace if you mess it up.
 
Worked fine for a while (months) then had another failure. Haven't tried cleaning yet, but only failed a couple of times. This last time it would go for an inch or 2 and stop. Then I cut off engine, restarted car, got a couple more inches. After several tries got the window up. Don't know why! Only failed a few times over several days, now ok again...BUT
 
Now problem others have developed--all dome lights and electric locks failed. Replaced fuses--no help. This seems to be a rare but repeated problem, per internet search. Only solution I've read about was replacing the ECM. Seems drastic! And expensive!

Electrical Problem with 2000 Sienna - Alarm/Door Locks by sponge1
Nov 24, 2008 (9:48 am)
Reply
Whenever I try to unlock the door (either using the keyless entry or by hand manually) the alarm system goes off. You must then turn on the veh. to get it to turn off. This just started the last two days (got quite cold suddenly). Also noticed that the door locks are behaving a bit strange. One other thing my wife noticed was that twice now when you try to turn on the veh (with the alarm going off) it won't turn in the iginition (like its locked). When you play with the locks (push lock unlock etc.) the iginition will usually then work. This does not happen every time! In fact, only my wife has had this experience (twice). Any Ideas?
