Driving into New Orleans today in my 2016 GS 350 from the North Shore and the air is working fine. Got in the car to come home and no air. It actually was blowing at full speed warmer air than it was outside. Double checked the settings on the Climate screen. Auto at 70. Air is on. Turned the system off and on a couple of times. Turned the car off. No luck. Called my local mechanic and asked if it could be anything easy and he said no and to bring it by for a freon check. I kinda of think it is electronics because I am having seat memory issues as well. I know they are probably not the same system but just worried I may have flaky electronics in general. Thoughts?

 

Sorry to hear this. I'm not sure what to suggest other than going to a dealer. About the only thing you could do on your own would be to disconnect the battery for 15 minutes to try to reset the system, but I'm not really sure if that would help or not.

 

If you are having problems with multiple systems, maybe check to see if a fuse blew? Other than that, dealer time will likely be needed.

 

Are the radiator fans running? Carefully check the the freon lines where they pass through the firewall, on the passenger side. Is one of them cold? There is a sight glass, poorly located in front of the evaporator, top left, drivers side. Should not have a lot bubbles in the freon as it flows. Is the compressor pulley turning? The fact that it went quickly from working to not sounds like a fuse or a rock damaged the evaporator, total freon loss, or something unusual. And I know it doesn't use freon R-12, I'm just old school
