Lumbar control switch

[relative4]

'07 335xi sedan. The little round 4-direction rocker switch for the lumbar controls spins freely, and regardless of where you align it, pressing it does not have any desired effects. Sometimes when you press it certain ways, you can hear the motors operating, but not in any meaningful fashion. There may actually be problems with the lumbar operation itself, but obviously I need to start with the known problem, the switch. Is anyone familiar with this problem? What are my options for repairing it? Thanks!

Sorry, shoulda googled before posting. Is it possible to delete a thread?

I guess I'm going to google this too then.
I have the same issue.

Bottom line is, the switch is $80-90 new or $10-15 used on eBay. Seat must be removed to replace the switch. Pelican parts has a procedure.
