My wife's wallet fell under power passenger seat on 2011 Outback. She moved seat back and wallet was caught between sound amplifier and outside track. By pushing and holding the switch the cable between motor and outboard rail tangled and broke. Motor and inside drive still okay. An easy fix? No Subaru wants $1,250 to replace entire under seat mechanism. The cable is not replaceable. So a misplaced wallet took down our new Subaru. Does anybody know if there's a way to replace just that cable to the outside track?
