How do you read trouble codes off display
A while back I came across some information on how to read trouble codes from the info screen by using a combination of buttons on the middle console. It puts you into some sort of service mode but, I can't recall how to do it. I've been searching for hours and can't find anything on this. Any help would be great. Thanks!

I'm not aware of any way to read trouble codes from the center display.
The only troubleshooting that can do is with the HVAC system.

The reason I was asking is because I have no A/C and the light just blinks. I found a thread that mentioned holding the AUTO & recirculating air buttons while turning on ignition and that worked. It displayed a 21 & 43 code. The 21 is solar related but I think it is because my car is parked in the garage. The 43 code I am looking into now. I also have a noise behind the dash which I think is the servo motor(s). Thank you for the response. If you have any other info related to my problem that would be great.

Code 43 is Air Outlet Damper Control Servomotor Circuit. Which is also commonly called the Mode Servo.

Thanks for the response. I also have a very high reading (red line) on the LOW side of A/C. Do you think it's the pressure switch, valve, clutch or possibly the compressor itself? According to Autozone the compressor did not engage. I also have been hearing a slight metallic noise under the hood but it doesn't last very long.
