Check that the DR fuse (20A fuse) located in the Instrument panel fuse panel is OK.
It supplies power to the Two Turn Unlock Relay, the I/P Junction Box (Door Lock Relay, Door Unlock Relay) and the Turn Signal Lamp Sound Relay).
Be aware that there is always a reason why a fuse blows, even fatigue may be a factor ;-).
Once you have replaced the fuse and if it holds without blowing straightaway, test everything that is powered by the fuse to see if it works OK without blowing the fuse again i.e. lock and unlock the doors using the key fob, by inserting and turning the key in the door lock and by operating the central door lock switch. Also test that the turn indicator sound now works (and that the indicators are still working)
