Motor failure is also a potential reason the sliding doors won’t open. And, unlike the sliding door cable, this isn’t something we’d recommend you do yourself. The part, too, will cost much more: somewhere around $1,200. Labor is slightly more expensive, though, at $280 to $360.
Circuit failure, too, can cause sliding doors to fail. If the electric circuit becomes overloaded, it can trip one of the fuses. Generally, when this happens, the sliding doors will still open but won’t latch closed.
Regardless of what’s causing the problem, you should tell your roommate what’s going on so they can take their Sienna in for a proper diagnosis. And we hope you can still pick up what you need from Facebook!
