The blower is located on the upper left part of the firewall. There are usually 4-6 bolts and a plug with 2 wires. Remove all bolts and remove the electrical plug, and the blower will pull out. Put new blower in old blower's place..re-install all bolts and electrical plug. That should get you fixed up!!
The heater core on a 1984 Cutlass Supreme is located under the blower motor on the passenger side of the car, under the hood. First you need to remove the blower, and the hoses connecting the heater core. Replace the core, re-attach the hoses, and put the blower motor back on.
It is on the Right side of the Heater Core Covering.

Below the blower motor
It is called "Blower Motor Resistor Pack". It will be located near the blower motor. Sometimes you just have to follow the wiring from the blower motor back to the pack to find it. May be located behind the glove box, side kick panel, or behind the dash.

Looking at the procedure in my 1980 GM service manual and comparing it to my 1984 G20 van, it apears to be simple process. 1983 should be very close. Negative battery cable must be disconnected. Coolant recovery tank and power antenna need to be removed. Blower motor lead wire is disconnected. Blower motor mounting screws (number may vary) are removed. Blower motor and wheel (cage) are removed as an assembly by prying gently on the blower flange. The sealer may be damaged in the process. The wheel can be removed from the motor. Apply new bead of sealer to the entire circumference of the mounting flange of the new motor. Installation is reverse of removal.
If by quit working you mean quit blowing, the things to troubleshoot are the blower motor, the blower motor resistor switch, or the blower motor speed selector switch. If by quit working you mean it only blows cold or warm air, the thermostat is probably stuck in the open position.
