Welcome back to 2CarPros. As you found the connector burnt I would replace it. You can usually find replacement pigtail connectors at parts stores or the dealer. The burnt area was most likely caused by the blower motor slowly failing. That increases the resistance which increases the current required to make the motor operate. That in turn causes heat which makes the connectors lose spring tension, that causes more resistance and the cycle continues until something fails.
