G320 cdi lumbar seats not working
Hello everybody, I have a problem with the lumbar adjustment for 1 week. I checked fuse 13, it's ok, I checked the pump, it's ok, but it doesn't receive the command from that circuit. I inflated the lumbar support, there are no leaks from the seat, I don't know if it's from the pump to the seat or if there are any leaks. When I inflated the seats, using the vacuum pump directly from the battery, on the "return" circuit, it was as if a vacuum was being created. Do you have any idea what else to do? Btw, I bought a pump from a W164, but that didn't work either..
