It worked one day, and just didn't the next. The light on the AC button lights up, the fan runs and air blows, but no click of the compressor clutch when I turn it on, and no idle change. Is there a fuse for the AC com0ressor clutch somewhere? Or other ideas?

Sounds like it is low on the coolant which causes it to only work part of the time. You could probably take the car to a auto parts store and at least here in the midwest, they can help recharge your freon/R22 so you have a good working air conditioner. If that is properly charged and leak free, then your air conditioner compressor might be going bad, but then you would hear a lot of belt squealing when it wasn't working. Most likely though it is just low on the freon/R22.
By the way, air conditioners don't have spark plugs......LOL
when a fuse keeps blowing it can only be one of two causes. either the consumer is loading the circuit too much due to a bearing problem or rusty component, or there could be a short circuit to ground. disconnect the blower motor plug connector and turn your a/c on like normal. if it blows the fuse again, replace the blower fan motor. if not, start checking the wiring for any exposed copper that might touch the ground-negative.also inspect all the plug connectors for water damage and corrosion.
I didn't know it had a light on the dash that said "cooling fan temp". My 93 doesn't. The cooling fans are controlled by the computer and turned on when the ac is running or when the engine reaches 220 degrees. A mechanic would check the fuse and relay for power and the fan motor for power and ground.
I've gone crazy fixing air-conditioners in cars. There is a control valve in the air conditioning system that often needs changing. I would suggest that as your next step because it is relatively cheap intervention. On my car they just changed the electronic command system costing $600. It didn't fix the problem. They then changed the valve ($125) and it did the trick. And finally, I once had a honda and they changed every piece of the ac. When that didn't work I searched the web which told me it was the button in the car. I had to change the whole heat ac control panel but I got a used one. Good luck and stay cool
My 2003 Toyota Camry AC often starts blowing hot air and the AC light starts blinking. I don't know why the following process works, but it does. Using the temp selector (left) reduce the temperature all the way down to Max Cold and then push the Auto button. It will start blowing out very cold air. After a little while push the temp selector to the desired temperature.
