E36 Power Lock Failure

[BM DUB U]

Hey guys

Figured it was about time to post my first issue =P.  I recently picked up a '93 318I.  When I first got it, it had appeared that the locks were working fine.  Then after unhooking the batter and clearing a Check Engine code, they had stopped working.  I'm guessing that the lock actuator just went seeing as it sounded irregularly loud.  If anyone could give me a hand with this one I would greatly appreciate it!
