Lumbar Support Adjustment Button Spins

Manual Transmission · 02-24-2019, 03:23 PM

The circular lumbar support adjustment button on my divers seat is able to rotate about 90 degrees. It's obviously not supposed to do this and the button doesn't seem to work when it isn't held in the exact right position. In fact I thought the button was completely broken until trying to hold it now. The lumbar adjustment is pretty much useless to me because of this. Is this a known issue that can be fixed? What parts would I need and will I need to do major disassembly of the seat to replace the broken bits?

You need to replace the entire switch module, part no. 61318352291 for the left side.
