#762 of 776 Sienna sliding door problems.
Jul 24, 2013 (12:19 pm)
The most common issue on these 2004 to 2010 Sienna power sliding door failures is the protective sheathing on the cables, and the hinges. The sheathing gets old and brittle and starts to crack and peel off. The sheathing then starts to bind up in the pulleys of the clutch, in the cable guides, or under the spool cap. This creates addition resistance when makes the motor complain, prompting most be people to think the motor is going bad. We have never had to replace a motor due to wear and tear. Its always the cable. As the sheathing peels away from the cable, it also exposes the cables to elements, Allowing the cable to rust and become brittle. Once it starts rusting it will break in short order. I do not recommend using the cable without the sheathing tho. The exposed metal cable can and will break the plastic pulleys of the clutch assembly. With no plastic coating on them to protect the thing plastic pulleys of the clutch from the steel cables, we have seen many many clutches broken beyond repair. Since we cannot fix the clutch, nor do we have an aftermarket replacement, the only other option then is to purchase the item from the dealership, and they go for over $1200 list price. So if you intend to keep the power sliding door feature in your car, I highly recommend you send them out for rebuilding before the pulleys in the clutch break.
The second most common problem are the hinges. The first generation hinges are very thin and a prone to bending out of spec. This can make opening and closing the door difficult, and also put additional stress on the motor and cables. If the issue is bad enough it can make the cable snap, as the cables are not running in their intended pathway. This issue as been dealt with by Toyota by way of making a stronger hinge, but as most people know it is not covered under warranty. Fortunately the price of the new updated hinges isn't too expensive, under $100. I'd recommend ordering this unit from your local dealer if you need a new hinge.
We have replacement parts for just about everything except for the clutch at this time. We also do cable replacements with brand new cables with a 90 day no hassle warranty. Contact us at BensonsAutoLA.Wordpress.com. Thank you!

Which cables do you cut? I've been looking all over youtube and the internet to figure out what cables to cut and can't find anything. I don't mind having a manual door -- I just don't want to cut something I shouldn't cut.

Hey guyz, Bensons Auto has just posted video instructions on how to remove the Sienna sliding door motors. It really does look pretty easy.

ADD US TO THE LONG LIST OF GRATEFUL PEOPLE! We used the PDF you mentioned and read post #321 on this log, both extremely helpful! Ordered the part ($77.75 + $17 shipping) from our Toyota dealership, had it in 2 days and tackled the project ourselves (no mechanical know-how). 2 hours, 5 minutes later, works perfectly!!!
It's worth mentioning that although the step-by-step PDF directions & pictures are a lifesaver , it doesn't tell you all repairs have to be made while you're INSIDE the van. We had to do this at first light because the summers in AZ are so brutal after 9am!
Also, just for background, we took our minivan to the dealership first who quoted us $875 to fix the Door Lock Motor Release Assembly. Then went and talked to a mechanic shop down the street that a friend works at, at they quoted us $1275 to fix it (Toyota won't sell them the actual part you have to buy the WHOLE DOOR KIT otherwise they won't warranty it).
This was by far the most helpful site and best leads on this door failure!
Thanks again, AZ parents

So, how do I tell what fix I need? On my passenger auto door, it opens and closes fine if you pull on the handle. If you press the button on the fob, it tries to close and then stops right away, and it wont open with the button either. Thanks.

that is probably the actuator. I paid about $100 for mine and it took about 3 hours being very deliberate.
I actually have a second one since there was a nick in the first one I bought so they sent another for free. I was kind of saving it in case it happens again, but we will probably sell the van in the next few months.
