You could use a closure. Just modify your code like this:

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
    };
})(marker,content,infowindow));

Here is the DEMO

                    });

                    const infowindow = new google.maps.InfoWindow({
                        content: contentString,
                        maxWidth: 200

                    //     infowindow.open(marker.get('map'), marker);

                    zoom: 4,
                    center: centerCords
                });
                addMarkerInfo();
            }

If you also want to bind closing of infowindow to some event, try something like this

google.maps.event.addListener(marker,'click', (function(marker,content,infowindow){ 
    return function() {
        infowindow.setContent(content);
        infowindow.open(map,marker);
        windows.push(infowindow)
        google.maps.event.addListener(map,'click', function(){ 
            infowindow.close();
        }); 
    };
})(marker,content,infowindow));

I am trying to add multiple markers each with its own infowindow that comes up when clicked on. I am having trouble with getting the infowindows coming up, when I try it either shows up only one marker without an infowindow.

Thanks, let me know if you need some more information
