I have a 2006 Toyota Sienna Limited, and right away the door would not slide open automatically. After doing several searches online, I discovered that the sliding door actuator is a common problem in Siennas. After watching a video on how to install, I ordered this part. I would highly recommend you watch the video first, and make sure it is the right part for the door.The video for the "5 dollar fix" was very helpful. He really goes through the process thoroughly. I opted to get the part, because it saved me some trouble. One of the cautions he brings up is the screw that connects the motor to the door on the inside has softer metal than it should for the tension, so you need to be very careful not to strip it. It will be tight, so be sure to apply plenty of pressure on top, and go very slowly. We were able to crack it, but in the video he stripped it, and needed to drill it out and rethread it.I like to buy genuine parts, because yo know everything will work right, and it will cause less headaches. After we got the door disassembled, the part went in smoothly, and has worked without any issues. I hope it works!
