I have a 2004 Accord EX Coupe. The passenger power window won't work from either door and the power lock button won't work either. However, the key fob locks and unlocks the doors. Could it be the master switches on the driver door?

 

Search for a thread (here or in the DIY section) about re-booting the "multiplexer" There's some sequence of wiper switch & key that forces it to reboot. I think the multiplexer is physically in the door master-switch.

Careful about instructions across different generations. 1998-2002 is 6th-gen and yours is 7th-gen.

Otherwise, look for bad connections at any of those door switches. Rodents chewing on wires near the door hinges?
