Check the blower speed control resistor pack, it is located in the air stream near the blower motor, that is most likely the cause of the inop blower, but be warned if the blower is drawing to much current due to wear the resistor will fail again, I believe the connector has four wires, 2 are heavy Gage

It is not the resistor that fails but the little thermal limiter next to the coils of wire that form the resistive element, it is round, looks like a little barrel.

Hi, First remove the radiator overflow tank behind the right fender well, you may also have to loosen and place the a/c pump aside. Jack up the pass side of the car, with a combination of below and up inside the fender well , you can remove the blower motor fasteners, then replace the motor. Advance auto parts has this assembly available with the squirrel cage included. This is not an easy job but will be very rewarding.

1.First, if your car has Air Conditioning, loosen the compressor, and take the AC belt loose. Remove it from the AC compressor pulley.
2.Slide the AC compressor as far as it will go, towards the fender well.
3.The plastic Radiator Overflow tank has to be removed. Remove the overflow hose, and remove the bolts holding the tank to the inner fender well. It's a little tough to get to those bolts. I use a 1/4" drive ratchet, 6" and 10" quarter inch extensions, plus a flex adapter. Use either the 6" extension, or the 10" extension, where needed.
The plastic overflow tank is twisted a little, as you remove it. The shape makes it a little tough, but if you move it around, as you bring it out, you can gently twist it out of there. Use caution, as this is a plastic tank, and may be brittle due to age, plus heat from the engine compartment.
4.Now look at the firewall. This is the area under the windshield, and in the engine compartment. Facing the windshield, look to the upper left corner. You will see a motor attached to a plate. The plate has five corners on it.
Remove the electrical connections to it. Lay the small wire harnesses aside. Remove the machine head screws that attach the plate to the blower housing.
The plate is attached to the blower housing with a gasket seal. This is a Black rope like seal, and is very sticky! Due to age, and heat, the blower motor plate may be stuck to the blower housing, pretty well! You may have to use a putty knife to help loosen it.
The putty knife is eased under the edge of the blower motor plate, and is worked around the edge. You may want to wear some type of protective gloves, because if you slip, your fingers/hand could be jammed right against that blower motor plate edge. This edge can be a hazard to your hand, due to the force when your hand MAY strike it.
Safety above ALL else!
Also should your fingers/hand get up against the sticky Black seal, you will get sticky residue on your hands, or fingers. Kind of tough to remove.
Also I advise using finesse when using the putty knife. The blower motor housing, can be damaged by the edge of the putty knife.
Now it's just a matter of installing a new rope seal, or using some silicon of a tube, to form a gasket on the new blower motor plate. Observe how the old one is, and form yours accordingly.
Bolt the new blower motor in place, reattach the wire harnesses.
Put the Radiator Overflow tank back in. Reattach the Overflow Tube. Move the AC compressor back over so you can slip the AC belt back on. Put the correct tension on the belt, by using the 1/2" square hole in the AC compressors bracket, and pull the AC compressor towards the fender. I use a 1/2" breaker bar. The correct method, is to use a belt tensioner gauge, to test the tension of the AC belt.

you will need to pull off the four retaining nuts holding seat in place. Measure the length and width of bottom support frames. Many seats are interchangable.
