    Ok, I'm having a hard time understanding you. So you are turning the sleeper blower on and you can hear it through all 3 speeds, but nothing comes out of the vent? If that is the case you likely have a either the squirrel cage has broken off the motor or the main duct is broken or massive air blockage somewhere.
