Help need help or instructions on how to fix leather seat electric leather seat lumbar support

I need that info too. My lumbar support works intermittently. It almost never works when I push the button, but every now and then will work.

Has anyone fixed theirs? I assume the pump can go bad or the wires can get loose?
