It's telling you the revolution sensor is not matching the revolutions of the engine. The ECU takes over and cuts current to the AC when this happens and the ac light will start blinking. A turn the AC of then turn it back on and it's not blinking tells you the problem is going to lead to no AC if you don't get it fixed.

What does a blinking AC light mean on 98 Sienna?
If the AC light is blinking in the Toyota 98 Sienna, it means that something is internally wrong with your AC, it has stopped working, and it is recommended that you take it to the dealer to repair. This is not a very specific answer, but that is exactly what it says in the user manual. I find if I stop, turn off the car and AC for about 15 minutes, then restart, it will work again, until a week later and I have to repeat the process.
