The handle broke on our 2000 Toyota Sienna minivan. To open the sliding door, we had to open the front door and reach around to the inside latch. Inconvenient, but we lived with it for a year. Why? The part is impossible to find except at the dealership, and they wanted $90, plus another $300 in labor to install it. Obviously, if it's that expensive, it must be a real hassle to replace, right?
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.
