Report: Air Conditioning Fault Due to Failed AC Amplifier
Lexus RX350 Problem
Model Year Affected: 2007
Average Mileage: 53,000 mi (26,000 mi - 95,000 mi)
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.

Actually, I have a Toyota Camry - which is essentially the same. The A/C would stop working and a/c light would flash. If I turned it off and then on again, it would work for a minute or so and then stop again. I took it in to the dealer and they first thought it was the compressor. After doing additional testing, which they claimed took hours, they said it is the a/c amplifier and the cost to fix it is about $750!
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
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.
