Hello all- I recently picked up a 2010 Prius and have no complaints except that the lumbar support wasn't functioning as expected, so I took it apart and the plastic gear in the wire pulley system decided to fall apart. Anyone know what the part number is for the entire lumbar support assembly? or the Motor with Pulley, or just the Pulley? I found a pic of the assembly and circled the problem part.... The motors working everything else is in tact. Just no way to adjust the lumbar outside of opening the seat and messing with it manually. Thanks!
