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

Leave it in the dealers parking lot overnight. Start it in the morning and drive right up to the service door. Crazy they won't fix it seeing the code activation in the history.

If the dealer can see it in the history, and no satisfaction, ie., lazy or whateva, find another Dealer.
