If the blower doesn't work check the fan circuit breaker in fuse panel behind kick panel on passenger side . The circuit breaker is resettable. On the top is a small hole. Use a small nail/ paper clip and insert into hole and press inward to reset breaker. Also check the blower resistor which mounts in the blower housing.

Here is a link to a wiring diagram that you can use with a voltmeter to trace your wiring to troubleshoot blower not working. The heater/a/c diagram for a 4AFE engine is Figure 6.

The resistor block, inside the blower duct is the thing that generally dies first.
When that dies, it will usually only affect one position on the fan switch, but it can sometimes just kill the whole thing.

That will probably the cheapest thing to change, and the easiest to check.
Where exactly it is located I don't remember, but I think it should be somewhere downstream of the blower motor. You should see wires going to a block in the duct from the blower motor.
Somewhere behind the glove box.

I would attempt to reset breaker just to rule it out. To find the resistor block look for the plug in harness on front side of blower housing.

i would guess that the blower motor itself may be bad and drawing too much power once it gets hot, popping the breaker.

If you reset it and it tripped I would then check the blower resistor. On mine there was corrosion on the terminals inside it and it caused the breaker to trip. Also you usually get a slight burning smell which is the resistor getting too hot .

It could possibly be a bad breaker, but I would say check the motor and resistor first.

Exclamation

do not ever try to outsmart a good working breaker, if it is working correctly, it is stopping the electrical system from disaster!
