Re: its really cold
Your blower motor is located on the passenger side under the hood, it is a round looking thing sticking out from the firewall. The first thing I would do is unplug the wires to it, and turn on the system, then check for voltage using a voltemeter, this will determine if the motor is even getting power. If it is getting power your motor is probably burnt out. If it is not getting power it could be a fuse, which sounds likely due to all the rust you mentioned...good luck...Let us know what you find.
