I figure since it's a honda product similar to our TLs y'all might know the answer to this question.

My fiance' has an 04 accord coupe. The power locks just started flaking out on her yesterday. When she hits the lock button they will both lock fine but then 2 seconds later you hit unlock or lock again and the locks wont budge. You wait 5 minutes or so and randomly they will work again. Basically they work only when they want to. Ive tried making sure the trunk is closed and all that jazz. You can hear the relays for the power door lock mechanism clicking but then the door locks will just move ever so slightly but not lock (or for that matter unlock).

HELP!!!

 

Could be several things, door lock actuator, drivers multiplex, or maybe a soft connection some where. If it doesnt work using the keyless entry its probably the door lock actuator. If it works then its probably a problem with the drivers door multiplex just stick something underneath the plastic piece on the door where the buttons are where you grab the door and pry it up it just snaps in, and see if there is a loose connection to any of the wire harnesses, if not that switch might be going bad which is the smaller drivers multiplex. Well if you cant figure it out bring it in and have an experienced tech look at it.

 

Whether you're using the keyless or the button it works half the time and the other half it tries to work but doesnt...When it doesn't work (whether from hitting keyless or button regardless) both the driver and passenger doors twitch a little bit but do not lock (or for that matter unlock)

 

My guess would either be the drivers door multiplex switch or the door lock actuator, its kind of hard to tell through just description but there are several tests to perform to tell which it is. But if i were to pick between one it would probably be the drivers door multiplex switch.
