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??
