I have not been getting heat into my cabin. It’s been blowing cold air once the engine reaches midline running temp. I have had it at 2 dealerships no and both tell me it’s running fine. The last one tells me the latest 2019 update changed the way the heat operates. I feel like I am going crazy because I have had it out to the mountains and again NO HEAT! I personally think it’s the thermostat but I am told nope it tests fine. So anyone else having heating issues like this or have you had the update?
