2004 GT, power leather seats, lumbar no workie
 

Hey guys -

A friend has a yellow '04 that he recently picked up, the power seat works every which way but the button for the lumbar support in/out seems to do nothing. Been digging around with no luck, is this a common issue or any places to start looking?

Next time we get a chance I want to pull the seat and see if I can discover anything obvious.

Thanks!
Dale
