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.
Air conditioner is blowing hot air. My repair person said this is a known problem with the Lexus RX350. It's a 2010. I am very upset. It's my second RX and I had the other for 10 years. I am loosing my confidence with them.
ac blows cold for a minute and then turns warm - the compressor turns off and the a/c button light starts flashing.
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.
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
Had hot air blowing out of passenger side. Lexus did diagnostic checks and finally checked this part and that is it. $1.030 to fix. I am livid!
Got a message "Error reading temperature". The air-condition stopped working almost immediately following the message. Wonder how much it will cost to repair.
Car ac blows hot air with check a c message occasionally for a long time. Recently, twice it has blown hot air then turned cold with no check a c message. Happened first time and corrected after 5 minutes. Second time stopped and restarted car and it corrected itself within a minute
Ac light flashing and air not funtioning
Purchased 2007 Lexus RX 2 weeks back from a retired Military personnel. He said he kept the car in pristine condition. Now we are getting check AC light on.
Message started appearing on the navigation screen upon starting the car for the first time in the morning, usually after a night outside in a temperature of about 50 degrees. This started about two weeks ago and continued for 5-6 days. It hasn't occurred since. The car was not taken to the dealer and it has not been repaired.
