I replaced the heater core in my truck klast year and this year the blower motor and fan quit on me so I replaced them both my switch is still working but no I have no fan. It worked for about half an hour when I first installed it then quit. What could be the issue? I've got power everywhere I was looking for a wiring diagram from the blower motor

There is a resistor and relay by the blower check to see if power is going in and out there. There is also a fusible link that could have burned out it supplies power to relay
