I have a 1999 Accord EX sedan. The automatic door locks are all messed up. When you hit unlock, the driver side front door unlocks and so does the passenger side back door, but the other two doors don't respond. Whether I am trying to lock or unlock those are the only 2 doors that will respond.

Any idea why the passenger side front door and driver side back door won't lock or unlock without manually pulling the locks up?

Thanks

 

might be the lock actuators. remove the door panel and ascertain that when you hit the button there is voltage reaching it, then verify on the other end if the signal is being sent out. the lock actuators do not last all that long and are about $35 to replace. there is one in each door.
