I could find the AC mode

[stephen8]

I am not sure if I did the wrong wiring when I installed my Google Nest Thermostat, please the attached phone. My heating control is good but I just could found my the cooling AC mode in my app. Thank you for helping me out.

Sorry I mean I couldn't find the AC mode, I only find heat mode.

I have the same problem.  A/C  was working fine and then the cool icon on the Nest disappeared.

Now I have no A/C:(

I double checked the wiring already and its good. Any Ideas?

Thanks

I finally solved the problem, the wiring is correct, what I did is to reset the nest thermostat to factory reset mode, then reset step by step to turn on the AC.

Post a picture of the original thermostat's wiring.
