Good evening,

I attached a wiring diagram for you to view. Check the fuse I circled for power on both sides.

If that is good, you will need a volt meter or test light to do some tests to see if the blower motor or the resistor is the issue.

We checked the fuses out already and they are good. So we will test the resistor and blower motor next. Thanks

When replacing the blower motor noticed the plug to the motor was burned. What needs to be replaced?

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.
