Hello I scan my 2013 z4 and I have a few issues that Im hoping to fix myself with a little help from you. Right now Im not able to open the trunk at all not even from the inside or the outside or the alarm control. Im unable to open the middle console also or the passanger door. I scan my car and this is the codes I got.

31E9 ELECTIC FAN LINE DISCONNECTION
A6D4 LOCKING RELAY, UNLOCKING (NEED RELAY LOCATION TO REPLACE)
A559 POWER BEEN SWITCH OFF (NOT SURE WHAT THIS MEANS

THESE ARE THE MAIN THREE I WANT TO WORK ON AND FIX ASAP. ANY HELP I WOULD APPRECIATE.
