1967 Lemans A/C Blower Motor Problems

[Blacksdieselperformance]

I have a 1967 Lemans with factory air. The blower motor hasn't worked for a while. The last time it worked, it was just on and off. If it did come on, it would just go off if you hit a bump in the road. There is a piece in the top of the air box on the fire wall that a few wires go to. The connectors that come out of the top of it are loose. So I'm hoping thats the problem. Anyone know what its called or where to get one? Havent really checked into it. Thought Id ask here. Thanks

blower resistor

That thing with wires hanging out of it is the blower resistor. It lowers the voltage the blower sees so you get lower speeds. And ya if its out you get nothing or high. Get it at any parts store.
