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.

My passenger seat adjustment switch went bad. The only function that works is the lumbar switch. So I have been wondering the same thing. Why is the lumbar the only thing that works.
