here are the possibilities w/o you giving us more info
1)pass side switch, driver side switch and remote dont work but door knob still "wiggles"=bad pass side lock actuator (this is what i think the prob might be)
2)pass side/driver side switch INOP and remote doesnt work and door knob wont "wiggle" i.e. move or make noise when you hit the lock/unlock button=electrical problem i.e. blown fuse, short to ground (which blows the fuse anyway), open in the circuit (a wire is cut) etc
3)pass side switch INOP but driver side switch for the pass lock works=bad pass side switch
4)driver side switch INOP but pass side switch works=bad driver side switch.
the window motor has nothing to do with the lock. it controls the power window. im assuming his window still works
