so hope someone can understand my ques. ok so i have 2005 Nissan titian, there is this little box that has something to do with the heater and radiator that had previously been clogged with some stop leak we used in radiator so we took it off cleaned it all good since then we got a new radiator (stop leak awful) when truck is running sometimes the heater blows hot but then turns cold and truck heats up if we hit that box sometimes it will fix it but was getting worse so we took it off and it was plugged again prob with the rest of that stop leak but when cleaning it out this little blue connector? came off, we have no solder and need truck can we make sure that connector is touching where it was and use super glue to hold it on??
