Power window on passenger fr. Side had a problem working . when you slammed door it would work sometimes. Now not working at all . AND DOOR LOCK DOESN'T WORK . PUT NEW MODULE IN .
Motor may have went out or loose connection which I doubt is the cause but may have came loose. Check guides and listen if you hear motor trying to operate, it may be in a bind.
Maybe connectors on regulator motor or door switch plugs corroded. Park Ave develop rust on guides and behind window sesls causing glass to bind and circuit breaker to open on motor
