since my car went into the bodyshop my lumbar support does not work. On closer inspection the wires which can be just seen when the seat in pulled forward were damaged so i got the bodyshop to repair the wires, they took the seat out etc. Now im sick of taking the car back to them because they just dont care, they have marked my leather, tore a bit of carpet and the inside was dusty from the paint job. I am a perfectionist though! So i just want to sort this myself. The motor can be heard working fine but the lumbar support just doesnt move in or out, it feels flat. What exactly comes out when the lumbar support works? Any ideas where to check?
