There are two ways to check this problem. With engine off, grab fan and spin it. If it takes a minute or so to stop, or feels easy to spin, the clutch may be bad. The other way to check is to start engine, and using a long metal pipe (or lug wrench) insert into fan. If it stops spinning, then the clutch is bad. If using the second method, be certain that engine is idling...DO NOT ACCELERATE!!!

There should be a schematic on the lid of the fuse box that tells you what each fuse is for, and the size of the fuse.

Let us deal with the two very separate problems here.
The problem with the blower motor is that the blower motor speed control resistor is burned out, when this happens all you will have is high speed setting. The blower motor speed control resistor is located right next to the blower motor in the air ducting. It has an electrical connector going to it with 3 wires, the resistor is roughly oval shaped and would easily fit in the palm of your hand. It is held into the air duct work by two screws. See picture below.

Hit the the bottom of the starter motor with a hammer while someone is holding the switch in the crank psition.If it cranks then you need a starter.Also you can check with a test light or meter and see if thereis voltage at the starter solenoid.The big wire shold always have voltage and the small wire should only have voltage when the switch is in the crank position.Good luck.

It should be a plug and run solution. The new computer may take a while to relearn all the input from the various sensors but after running a while all will be well.
