The power lock on my front passenger door of my 2003 accord doesnt work, anyone know how to fix this?

 

You mean when you use the power door lock button/alarm the passenger door does not lock or open right? If so, check for power at the wiring socket on the lock actuator. If it has power then you have a dead actuator. You can purchase one from Honda for around 60-70, if you know a Honda employee its 30-45.
