Default What does the "pelvic support" button do on the driver's seat?

Like the title says. I have a 2015 LS Crafted Line and cant figure out what that button completely does. I do feel that pushing the 4 way button forward and back increases how much the seat pushes into my lower back but I cant figure out what the up-down direction does. I can hear the motors but I dont feel anything.

Its the power lumbar support. The up and down moves the lumbar support up and down.

Im wondering if mine is broken. I dont feel it moving up and down despite the fact that I can hear the motors.

it breaks easily and it cost $1500 to repair at the dealer, hopefully u r under warranty. If not, search the forum. I have seen people buy and replace only the motor that brakes rather than replace the whole mechanism
