2008 CTS-4....great vehicle. However, today and all at once the driver's seat position memory, both front seat heaters, both fron seat cooling fans and the park assist all stopped working. The park assist reset refuses to allow me to swith it back to "on". Sounded like a fuse but the manual lists no fuse for any of these items (there HAS to be a fuse for them). Any one have any ideas?
