The electric adjustment on seat doesn't work after replacing new seat bushes on my BMW Z3. What have I done wrong as they were working before, checked all electric connections and they are OK?

SOURCE: Will the wheels from a BMW Z3 M fit a 1999 BMW Z3 2.8 ltr roadster?

yes they will you just may need to use a wheel spacer

SOURCE: BMW Z3 WRONG UNLOCK RADIO CODE HOW TO GET THE RIGHT ONE

If the radio is displaying code wait, or wait, then the ignition and radio must remain on for 1hour. I would contact a dealer within the USA and provide them with your radio serial number. The serial number can be displayed in the radio by pressing and holding down the "M" button while turning on the ignition.

SOURCE: The electrically operated seats on my BMW Z3 2.8 roadster (1997) move approx. 1cm. backwards or forwards when accelerating or braking. Does anyone know how I can fix this problem?

Bushings in seat are shot. See this link: http://www.youtube.com/watch?v=DM4KSnA58EI

SOURCE: heated and cooled seats quit working. won't work on either driver's or passanger's seats. checked the fuses and relays and they are all ok. what's wrong?

Remove fuses 10 and 11 in the underhood junction box. Leave out for 5 minutes then reinstall. If the seats start working your Zephyrs dual climate control seat module will need replaced.

SOURCE: driver seat and steering wont adjust on my 95 740il

here's what you have to do:
#1. make sure the fuse to the seat adjustment is not blown, its usually a 10 or 15amp fuse.
#2. unscrew the cover to the controls on the driver's seat and make sure the harness is not loose or
broken, if the harness fails to attach to the control board correctly the steering wheel and the
seat adjustment will not work, this harness tends to come loose and even brake over time due to
the constant movement when you get in and out of your car.
I hope this solves your problem.
