hey people i have a 1991 corolla 1.6 4a-ge engine and my aircon is not working simply when i got in side and turn it on nothing happens there isnt anything blowing the a/c button and everything is on i check all fuses and working 100% does anybody know and relays etc that can cause the blower i presume to stop working.

thanxx all help appreicated!

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.

thanx people

The Circuit Breaker Is getting Power So should i still reset it or could it be another problem thanx for any help is appreciated!

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 reset the breaker and it worked
but then it stoped working after 1 hour so im gusing the breaker needs replacing
thanx for yur help ppl

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.

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

installed yuu breaker and new blower and is working 100% so far!
hopefully problem fixed thanx 4 all advices!
