I've got a 2001 chevy metro. When you do the auto door locks the pasenger door doesn't lock but all others do. The same on the pasengers door switch it'll lock every door but that one. Where would I look to fix it.

complex system,
but fix the key problem first.
Honda sells the FSM ,buy it?
alldata.com has this chapter, read how to diagnose it.

did you try to pres it twise

the power lock actuator is bad and needs replacing.

need new front door actuator

could be damaged wires in the door pillar to door rubber boot ,also the self locking mechanism will not work if this fault is prevalant ,personaly i do not like self locking vehicles as i do feel they are dangerous in a accident but??

You have a slave door electrical sysyem ... ie the drivers door is the Master door with a mechanical lock ,,, which sends an electrical trigger to All the other doors.... the passinger door does not have the trigger signal for the rest of the doors, but can operate via a Key .(or elec trigger from drivers door) So to recap Driver door (master (no motor) all others triggered by Drivers door . So dud passanger door motor. Good luck

you need to check the wire harness from the vehicle to the door for broken wires.the harness that goes through the door post and into the door gets a lot of flexing and will eventually break the wires in two.if this is not the case ,you may just need to replace the switch.

#1.. replace horn
#2.. check power & ground to W.W. pump.. if present.. replace pump.. If not, repair wiring.
#3.. replace door lock/unlock actuator.

Check your wires first if tight It is probably a bad switch asembly

i would say it isn't a fuse its a relay or triangle shaped device plugged into your fuse block because all them uses more watts that an ordinary light.
