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.
It is possible that your Sienna does not have a spare. Mine was equipped with roll flat tires (RFT) which eliminate the need (in Toyota's mind) for a spare. Saves them a few cubic feet which they can then tout in advertising. i have a 2004 totoya sienna and the spare is under the passinger rear slider door the carpet has a little flap right behind the passinger seat when u open the little flap or carpet there a nut that u turn and the spare will start too come down underneath
Try checking the handle on the inside of your slider. I have this problem with my slider. If the slider gets opened from inside the villager the handle sticks amd the slider wont close. I suggest using white lithium grease to help free up any stickyness of the handle. There also a possiblity that you have an item in the track on the slider, check that too.
To remove the door handle from a BMW z4 you will need to have special tool or a hook tool to grab the slider and pull it towards you to release it.
all the slinding rear windows that i put in you had to replace the whole rear glass
