I am trying to figure out what might be causing my heater blower fuse 25 to burn out. My heater fan is currently not working. I've checked other responses in regards to the resister box underneath the right side of the dash. Would this box have any relation to the fuse for the blower? I am trying to fix the heater before it gets too cold. By cold I mean it can get -30F

Thanks Guys! You've always helped me out in one way or another.

Have you tried supply a power and ground directly to the blower motor?
