remove back shell from seat
Anyone know how to remove the back shell from the seats so you can get to the bladder motors etc.? The pages in the shop manual 1) just say "remove the shell" and 2) have a picture of a different seat.
Thanks in advance for helping.

did you ever do this? I am wanting to attempt to repair the massaging and dynamic seats that has a pressure issue. The pump is fine, the air is leaking somewhere though.

Thanks!
