Tip & How-To about Chevrolet Cavalier
On most vehicles when the heat stops blowing it's usualy not a fuse or a relay but the blower motor or the blower motor resistor.
Here is a good way to check if it's the blower motor. Disconect the plug going in to the blower motor, Now run two long wires from the battery one on the negitive and one to the possitive. put power to the blower motor with theese wires, negitive to one post and possitive to the other .Does'nt matter what post you hook to the blower motor will just spin the opisite way. if the blower motor spins then you can rule out the blower motor and suspect the blower motor resistor is bad. to find the blower motor resistor all you have to do is follow the wirring from the blower motor. The resistor will be at the end of the wirring for the blower. The resistor will be mounted on the heater box near the blower motor and is usually held in by two screws.
