The year, make and model info would help but generally the heater blower motor resister is located close by the heater blower motor.
If you are referring to the blower motor squealing, then I would suspect the blower motor bearings have failed.
blower motor bad or no power to it chech fuses blower switch blower motor
Could be, heater blower motor has failed. blower motor fuse is burned out. blower motor speed resistor is burned out. blower motor switch is bad. or, if the blower motor works but you have no heat it could be, cooling system is low on coolant. thermostat is stuck open. heater core is plugged. temp blend door actuator is faulty.
A bad heater blower motor resistor would effect one or more blower speeds other than high.
The only relay in the heater system would be for the high speed function of the blower motor. That rely would be located under the hood, on the firewall, close to the blower motor resistor.
Bad bearing in blower motor?
Replace the resister, if that doesn't work replace the blower motor.
Blown fuse, defective blower motor resistor pack, defective blower motor, a bad switch, or disconnected or loose wiring.
Is the blower working? need new thermostat ADD-ON: if nothing happens when you turn it on it could be a fuse. Check your manual for the location of the fuse panel. Check the fuse for the blower motor or heater depending on how it's labeled. If you do not have a manual check the link I added for places on-line where you can find downloads.
The relay on the heater/blower circuit on a Ford Escort MK6 is probably behind the glove compartment. There are two popular places that Ford puts its heater/blower relay switches. The other place would be next to the blower motor itself.
