Are you saying the blower motor doesn't blow air?

There should be a blower relay on the firewall. The wire colors are orange--red--dark blue--purple--black. You should be able to do some testing at the relay.

You could also run B+ and ground to the connector for the blower motor, to see if the motor will run. Use an inline fuse.
