Hello,
I purchased a new 2010 Lexus ES350 in November 2009 equipped with Navigation System. It barely has 10,000 miles on it. Now I am having problems with the AC. Whenever I run AC it blows cold are from the dashboard area but after running 10-15 minutes it starts blowing hot area under the dash over my feet area. I mean it is very very hot. I tried all the different settings that were specified in the manual but it did not help. I took the car to 2 different dealerships and they did the diagnostics and said the system is operating normal and is working as it was designed. They do agree that the hot air is blowing from the feet area but their explanation is that car is trying to maintain the temperature that I set. When the temperature reaches that setting the AC tries to maintain it and to do that it blows hot air from the bottom because the heat rises. I am very concerned about what is going to happen when the cold weather arrives. Is it going to blow the freezing cold air on my feet to balance the temperature? At this point I am trying to find out (1) if I am the only one who is having this problem (2) if other people have this problem what was the solution and (3) what should be my next course of action. Any help/suggestion is greatly appreciated. Thanks in advance.
