Does anyone know how to remove the lumbar support in the driver's seat? I have had alot of back pain driving my M-o, and have tried almost everything. I seem to be better in the passenger seat which does not have the solid rod for the lumbar, but a spring. I'd like to remove the lumbar and experiment by using a spring instead. I'd take it to my Nissan dealer to take out the lumbar but I know he would charge me a fortune.
