The temperature gauge stops working at the same time AC stops working.
ECM reset worked for a few miles and stopped.

Hello,

It sounds like you have a coolant temperature sensor that is out causing the computer to shut down the AC. Here is a guide to help you see what you are in for when changing the sensor out and the location of the sensor below:
