I have seen the blower motor resistor go bad or the connection get overheated, here is the location of the blower motor speed controller so you can check the connections for heat damage/melted and I would check the electrical connector at the blower motor as well. I have marked in red the connection point I need you to inspect. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
