I have a used 2001 Cadillac Seville (Canadian) with a strange problem:
Any of the four doors can LOCK all four door locks by pressing the electronic lock button. However, only the DRIVER can UNLOCK all for doors by pressing the electronic unlock button. If any other door presses the electronic unlock button, nothing happens (but they can unlock their own door by pulling the mechanical door lock button).
My dealer says this is by design - but it seems strange. Any other Seville owners have this problem/feature??
Thanks, Mike
