Subject: power locks
Question:

Never had a problem before but today the power locks do not respond when pushed. I have a 2003 Diamante, automatic. When I look in the book I do not see a fuse listed thatt I can check and possibly change. Could it be an electrical problem that would require me to bring it in for service? 

Answer: Rick,
The fuse for the locks is most likely part of a multipurpose fuse that controls several items (dome light, floor lights, etc.). The main switch for the door locks is in the driver side control console. You should have a mechanic inspect the switch and make sure there power getting to it and that there is proper connectivity in the switch.
Good luck!
