High pitched squealing or grinding is an indicator that the blower motor is about to die, I'd say yours has probably done just that.

Toyota Tercel belts are squealing

I have been having the same problem with the alternator belt squealing, most noticeably, when using the heater fan , accelerating, turning the headlights on. I have a 1997 Toyota Tercel CE 1.5L 4cyl with no A/C. I just tightened the belt tight enough that there is no give to the belt and it does not squeal anymore.

I also used a Goodyear Gatorback from Napa belt which seems to be nice and quiet when tight enough.

The fan does not turn on but the furnace does appear to heat uo

Try turning the fan on manually at the Thermostat by clicking "Fan On"...if thiis turns the fan on...leave it running and you will have heat till a Service Tech can come out....if if doesn't work you will req a Technician to have a look . Likely if the furnace is fairly new either the Relay , Circuit board relay or the motor itself is Defective.
