I purchased my 2012 650i convertible last year and the driver's side lumbar didn't work.

I can't hear any motor running so I purchased a new pump and pad from eBay. (they look brand new and were an exact fit. Came with the white junction box too.)

I just swapped them out and still no luck.
Is there a separate fuse for the lumbar pump? Or, could it be the seat switches that have gone bad?

Any help is appreciated.
