airconditiioning

Just had the same thing happen to me. Check the level of gas in the system; mine had none and therefore the a/c clutch would not engage due to the low (nil!) gas level.

Have you tried the fan on maximum speed ?
If it works on maximum and not on the other speeds then it is a resistor module that has failed.

Another way to check if it's due to low gas is to turn the air switch on, then under the bonnett you will have a high and low pressure switch which will prevent the compressor from cutting in if the gas is low this is to safe guard the compressor from running dry as the system has oil put in it when the gas is put in. Find yourself a piece of electrical wire and bridge the high and low pressure switch. If the compressor kicks in which you will hear a clunking / tapping noise this is the clutch on the compressor engaging then that will indicate to you that it is low on gas if not you have another problem. BUT if it is a case of low gas this should not affect the running of the internal fan. This fan should work with or without the air con switch on or if the system is low on gas. The air con button should only light up when you push the air con button plus when you turn the fan on. I think you have another problem if the intenal fan is not working which will stop your air con from working. Is it genuine air/ non genuine. Also check the relays under the bonnett should have written on the cover air cond/ heater fan. Otherwise stick your head under the dash around the heater/ aircon box make sure no wiring looms have separated. If it has an electric fan in front of the radiator and this is also not working as said you have other problem fuse/relay. If this is genuine air and the fan between the grille and aircon condensor is not working this is another issue as toyota do the wiring so that even if the electric fan is not working it will shut the system down. Also check for relays/ fuses for cooling fan which will be for the one infront of the radiator. Hope this helps you out. I know a resonable amount air con in toyota's as I fitted them for four years.

If you have lost the air con gas, you could be up for big bucks.
I had the same problem on my 80 series recently, no gas. The problem was a cracked/broken pipe connection on the condenser radiator.
An air con repairer can easily check for gas leaks.
The condensers are not worth repairing as it will remain a weak spot subject to cracking again.
New condenser, remove and fit, regas, looking at around $650

Good luck

You say the interior fan, so I assume you mean the one "blowing" air into the cabin (hot or cold). I would suggest its the bushes in the fan or maybe something wrong at the switch. If you can get to where wires connect to the fan you could test for power getting there. I have replaced the bushes on mine a couple of times now. Couldn't get genuine ones, so I went to an auto electrician and found ones of similar size and filed them a bit so they fitted in. Losing gas from the aircon will not effect the interior fan.

If your interior fan and your aircon has died then I would be looking at why the fan isn't workng first. As if the fan is not on then your aircon won't work either. My money is on it being an electrical problem. As was said above check to see if the fan works on full speed. If it des it is a dead resistor block. If it doesn't work on any speed then check all the fuses (again) then if still nothing pull the plug off the fan and check for power with the switch on. If no power check for power at switch (both sides).

I would guarantee that it will be a cheap but perhaps time consuming to find electrical problem. (unless it is the fan itself (expensive) but that shouldn't stop the aircon compressor).

On some of the toyota`s they have a fusable link to the blowers that goes. It is above the fuse panel for memory, cost is about $30.00 and I think toyota genuine are the only one`s you can get.
