I have the same problem on my 05' Sienna. My mechanic showed me that it was the door hinge making the noise (soon your window will not open unless door is open). My mechanic said he has seen this before, but Toyota dealer has to fix it. They want $1K to fix, so we are living with it. Toyota is going down hill.

To fix a 2006 Toyota Sienna power sliding door, first check the fuse associated with the door's power supply, as a blown fuse can prevent operation. If the fuse is intact, inspect the door tracks for obstructions or debris that might hinder movement. Additionally, examine the door motor and wiring for any signs of damage or disconnection. If these steps don’t resolve the issue, the door motor may need to be replaced or the system recalibrated by a professional.

Replace the handle. You will need to remove the door panel to replace the handle. If you can't do this yourself take it to the dealer. They should charge you about 1.0 to 2.0 hours labor to do this, plus the part.
