Someone was asking me the HVAC codes. So I made a quick video about how to show you how to get the HVAC (air conditioner) diagnostic codes for your late model Toyota or Lexus vehicle or truck. This video shows the procedure on a 2017 LX570, but the same procedure will work on most Toyota and Lexus vehicles that have an "Auto" button and a digital temperature readout.
If you notice, my error codes were still stored, I had code 42 and 49. I cleared them, took it for a drive while changing AC settings, and then checked to make sure the codes did not come back.
