Last week the rear handle also broke. And the dealership wanted another $390 for that one! Stupid plastic parts! But I found a website showing how to bolt the broken piece back together. It also showed exactly how to disassemble the door - only 3 nuts, 5 screws, and a few plastic clips.
A few hours and one trip to the hardware store later, and I had it fixed! Better than new!
"Surely," I said, "the sliding door can't be much harder!" Turns out, it's even easier! A grand total of three screws and one panel held on by plastic clips are all that separate you from a fully functioning handle.
This same procedure should work for any of the Siennas made around the same time.
Step 1: Tools of the Trade
- 10mm socket and wrench, for removing bolts and screws.
- Flat head screwdriver, wrapped in tape to protect the paint, for prying things apart.
- 3/16" (or thereabouts) socket. Size doesn't much matter, it's just a handy way to push out a plastic rivet.
- Flexible retracting grabber thing, for fishing the broken piece and any dropped tools or parts out from inside of the door. A willing 3-year-old accomplice with small hands, or a trained rat, might make this unnecessary.
- Clamp, for holding the pieces until the glue cures.
- Utility knife, for scraping off the excess glue.
- Adhesive. I used Locktite's Sumo glue. You could use Gorilla Glue, JB Weld, or epoxy. Something thick is handy here; super glue probably won't cut it.
- Small rod of some kind. I cut the head off a bolt. A large ringshank nail or even a wooden dowel might suffice.
