yes, the fan could be bad

This is an easy test/fix.  The fan should be located on the passenger side of the firewall, looks kind of like half a coffee can mounted with 3 bolts to the firewall.  Two wires run to it.  Apply 12 volts with test leads across the fan motor and you should have some action from the motor -- if not, replace it.  A new unit costs about $15.  If you have movement of the fan when you apply the test leads, but not from the switch, you may have a bad blower relay or short in the wiring to the fan.  

The entire control panel could be bad. Mine went bad for no reason.
