I had my 01 roadster in the shop for some rocker repair/repaint. Since then the lumbar switches on my sport seat do not work. I took the seat out and made sure the connectors were properly connected and they were. Is there a fuse or a circuit breaker that controls this function? The main seat control(back-forth/up-down) works fine. Thanks,bloggers. BTW the rear wheel bearing became a shop job when the master nut REFUSED TO BUDGE. Got charged $130 labor(I provided the part) which wasn't bad. I figured that a six foot breaker SHOULD work....but it didn't. Oh well.
Too bad there's not one blogger who could help. Paid the local shop ($100)who replaced a circuit breaker. Guess I'll stick to exhaust tips ,nose bras, and cool shifter ***** in the future. I am obviously disappointed.
Had the same problem with my lumbar. Turned out to be a bad lumbar pump/module. The lumbar pump comes with the module as one unit. There is a fuse for it that I would check first. It is identified in your owner's handbook. What you can do is listen carefully while you press the switches for any clicking sound. If you hear any noise then your problem is the lumbar pump. Good Luck.
