I have a 2004 Mazda3 Sport GX; and a few weeks ago the locks on the 3 passenger doors and the hatch started to act up. Every once in a while, they would only lock but not unlock when using either the fob or the power lock control on either front door. The front driver side door unlocks and locks perfectly fine.

As of a few days, this issue has become a permanent one. i can't unlock the hatch or any passenger doors on my car... The dealership tried telling me that it is the actuators on each of the doors and hatch; but, that makes no sense to me since the locking function still works and they all stopped working together.

Anyone have any ideas as to what could be causing this?

Thanks!
Fred
