A/c Light Flashing

[mofotallity]

Hi, I have a 2004 RX330 and the air-conditioning has stopped working. When you open the climate menu the A/C light just flashes.

Does anyone know what the problem is or how to fix it?

As explained in your owners manual, a flashing A/C button light means that the A/C compressor is not operating. The problem could be simple but it will probably take someone familiar with A/C systems to diagnose the problem. A Lexus dealer or independent shop specializing in Lexus/Toyota may be your best bet.
