Apply power to the clutch coil and see if it will engauge. It is not uncommon for the coils to fail. I am making the presumption that you have checked the fuses and have power at the relay. ---

It may be low on Freon, you’ll probably need to get it checked out. I’d pay a professional to do the work. ---

The blinking light means the control module (yes, even a control module for A/C and heat) has detected a problem. A high-end scanner, like at the dealer, can pull codes and point to a fix. Some are able to dislay codes with a procedure, but you’ll need to find that on a Toyota forum. A simple code scanner cannot pull these codes. I found a similar solution for my Ford on a Ford Explorer forum complete with code definitions. Saved me a lot of money and the fix only cost me $60 and two hours on a Saturday. ---

The scan tool is unnecessary to pull codes on the a/c control on this car. You very simply turn the car on while holding the recirc & auto buttons. The code will be displayed on the a/c screen. Code 22 is for the lock sensor and most often caused by a failed coil. Post your code if it is something different. ---
