Hi,
I have the IS350 2006. My lumbar support button on driver seat doesn't work. Anyone have the circuit diagram of it? Thanks a lots.

Try moving the seat all around using all of the other functions of the seat. Once done, try the lumber again to see if it works. I randomly lost the use of my lumbar for a period of time; but then it randomly came back. I have no idea as to why, but perhaps the moving of the seat around helped. Good luck!

Thanks, I'll do that.

Same thing here. I need to hit a few switches before I can get the lumbar to work. I'd like to say the switch is going bad since when it does work, the motor inflates/deflates it.

Thanks, guys.
I'll try it tonight
