When I start my 2020 Ram 1500, 5.7L, in the summer my Auto Start/Stop indicator will be on with an exclamation point beside it. When that happens my AC does not blow cold for anywhere from 15 to 45 minutes. I get an engine code of P0073, bad ambient air sensor. Took it to the dealer because the truck is under warranty. However, by the time I get to the dealer everything works again, so they would not fix it. Even though they could see the code activation in the trucks history. I have read others have this problem and changing out the sensor on your own doesn't really solve the problem. Has anyone found a fix to this issue? Thx
