Heater/AC Blower Speed Resistor Noise

My 82 K10 Heater resistor is screaming! I't has been making this screaming noise intermentantly for the last year but today it would not go away. I have tried replacing the relay below it but the new relay causes fuses to pop so I assume the relay is bad from the manufacture. Is my resistor bad or my fan? When it isn't screaming the fan works great, but when it is the fan is slow and weak..
