Here is what I used if you are using many markers in a for loop (Django here). You can set an index on each marker and set that index every time you open a window. Closing the previously saved index:

markers = Array();
infoWindows = Array();
var prev_infowindow =false;
{% for obj in objects %}
var contentString = 'your content'
var infowindow = new google.maps.InfoWindow({
            content: contentString,
          });
var marker = new google.maps.Marker({
               position: {lat: {{ obj.lat }}, lng: {{ obj.lon }}},
               map: map,
               title: '{{ obj.name }}',
               infoWindowIndex : {{ forloop.counter0 }}
          });
google.maps.event.addListener(marker, 'click',
            function(event)
            {
           if( prev_infowindow ) {
               infoWindows[prev_infowindow].close();
                }
                prev_infowindow = this.infoWindowIndex;
                infoWindows[this.infoWindowIndex].open(map, this);
            }
        );

        infoWindows.push(infowindow);
        markers.push(marker);

      {% endfor %}
