My AC light is flashing on my RX 300, I can hear the compressor come on, but hot air blowing and light is flashing

If your Accessory belt gets wet (driving over large puddle) then the A/C light blinks, but it goes away the next day as things dry up. Lets hope this is the case.

There is a test procedure that the dealer has and I vaguely remember coming across a blinky/flash count procedure. Maybe a member knows how to lead you there.
