Sound like you need to troubleshoot your blower fan and its circuit. Start with the fuse that controls it and, if good, keep working your way to the fan itself. Also, the fan may not seem like it is working if the ductwork that diverts the airflow is not functioning. The diverters are usually run from vaccuum lines that are controlled by your AC/Heater control panel.
