air con/fans don't work

my airc con has been dead for about a month and the fans don't work the problem i feel is with the fans hence the aircon doesn't work. We thought it was just the fuse which had blown before and i finally gfot round toi removing the passenger kick panel today to check the aircon fuse, to find it perfect, checked all othyer fuses in the car and the only one blown was the horn/hazard falshes and replaced it and it had no effect on the fans.
Anyway can anyone think of something else that is simple that would stop the fans from functioning, they were starting to get noisier just before it stopped working so I'd say they just carked it.
Anyway something else to note in the fuse box on the passengere side there is an unused circuit that was labelled seat warmer, the circuit is not there but found it funny that an 85 car would even have the provision for a seat warmer.
The fuse box does not appear to be blown either very clean not corrosion or burnt wires so thats not the case. Anyway any help would be appreciated.

Hi,
If you have the aircon switched off, do the fans work? If you set up your demister to blow hot air (assume for a minute it's a cold winter day) do the fans work then?
If they don't work, and the fuse is okay, then I'd check the connection points to the fan. Make sure it has a good earth and do a voltage check with a multimeter to see that 12v is going to the actual fan. Also, check the fan, with no power supplied to it, and see if it turns freely. If it's binding then you'll either need to get a new fan motor or try and get some light machine oil into its bearings. Initially you can use as a little bit of WD40 to free up the fan, but WD40 is too light for this type of anti-friction - so after it's freed up a bit then puit a few drops of light oil into the bearings. I'm assuming here that you can get into the bearings.
If the fans work okay on their own, but don't work when the aircon is active, you should look at your aircon switch. Not the actual switch in your car, but the aircon should have a centrifugal clutch or some other mechanism that activates at a certain rpm. If this doesn't work then the aircon compressor won't start - but, I would of thought the fans would work 'cos they are no dependant upon the aircon being active or not, unless there is some control logic in your electrics that won't start the fans if the aircon compressor ain't going.

isnt there a circuit breaker in the passanger kick panel.
to reset it you have to get something like a needle, I have used a drill bit and push it in the little hole on the big black thing, have a look in your manual first it tells you how to do it from memory.

the fans don't work all, i cehcked the passenger side kick panel yesterday and the fuse for the aircon was fine, i didn't see any reset thing on the box but will check either this afternoon or monday. Went to toyota today to get a new radiator cap, and asked them and the guy said that there is a resistor dfown near the heatercore that contorls the fans, but usually the fans won't work at low speed when it starts to go and my fans don't work at all, it would be a bitch to work on anyway.
If its gone its 80 bucks to replace. He said to first check whether the cricuit was working and then look at replacing it. Anyway thanks for the help, see what happens and if bugmans idea doesn't work i be back for more help.
Whern i was looking for the fuse box originally i found the thermostat for the aircon, found out why it seems so cold (i like it that way), it has been set to the coldest possible setting, any thanks for the help

put direct power into the fans and if they still dont work turf them and get new ones. thats the easist way to test them. if they work start looking at relays. if the aircon compresser does not turn on get the gas checked if you have a leak or low preasure the compresser will not engage. hope this helps...

it has to be ther fans the aircon is fine the only reason it doesn't work is cos it won't turn on unless the fan is on thats just my feeling anyway, river are you gonna be at kiama tomorrow if you are might have a chat to get a better description of what i can check, all else fails i'll get my uncle to haved a look at it he has had three coronas one being mine and will probably fix it in minutes.

Hi,
No, I won't be at Kiama tomorrow. My wife and her family are catholic and, from what I gather, Easter has some religous significance. I was gonna go down the Jambaroo today but the weather closed in a bit and I didn't feel like drving through shit weather for a few hours.
In regards to the fans, talk to some of the lads while you're down there at Kiama and I'm sure they'll offer some good advice. Also, be careful when adjusting your aircon to be at its coldest setting 'cos this means the compressor will run more often and shorten's its life.
Take a multimeter down there with you and get someone to test the power to the fans and to do some other basic diagnosis of the fault.
