RookieAfter owning the car for a week the problem started. The heater display goes blank, all functions with the heater/AC will stop. It will then come on again and work perfectly. This seemingly happens at random. Now the same thing is starting to happen with the stereo system.

RookieSame issue, my display is blank for both heat and a/c and nothing is responding. I replaced the display and it is still the same problem. I finally decided to go to the local Lexus dealership and ask. I didn't much help but he recommended looking at the fan relay. I will update progress.

RookieHad to turn on heater for a few days. Now, the ac won't get cold. Freon and everything is working perfect. Just heat comes out of the ac instead of cold air.
