The air conditioning light may flash or an AC error message may be displayed. Our technicians tell us this is commonly due to a fault with the AC amplifier, as revised part is available to correct this concern.

    My 2007 RX350 will on occasion show a "check air conditioning" warning that appears on the Navigation display. When this happens it is usually after the car has just been started and it then will not blow cold air. If I cycle the air conditioning on and off the air begins working fine again. Looking for what part to replace and where to get it.

    Check AC warning light came on when car first started about 2 weeks ago. It stayed on for about 5 seconds. AC has worked fine and error message has not reappeared. I'm trying to get an understanding of what caused the problem and the cost for repair.

    Same as one of the prior reports: A/C will start blowing hot air, and message appears on navagation screen saying 'check air conditioner'. We've driven to Lexus Service under this condition, and while the 'message' was still 'on'...they ran the 'diagnostics'...which said 'nothing is wrong'. Obviously the 'diagnostics' are wrong too. After several attempts, Lexus still can't repair
