My 2002 Santa Fe started having problems yesterday. When I use the key fob to
lock the doors all of the doors lock except the front passenger door, then the
lights start to flash and stop and then start again. If I lock the doors with
the key all of the doors lock except for the front passenger door, I can
manually lock it but then the suv starts making noises like it is locking and
unlocking itself. The only to disable either problem is the disconnect the
battery so it does not die.
