What am I doing wrong? Heat is on but blowing cold air.

[Shopaholic]

Hi All!
1 week in with my new Telluride. We live in Minnesota so it gets cold this time of year. When we start up the vehicle it heats up. After we start driving for awhile, or if any changes are made to the climate, it starts blowing out cold air (front and rear). We have tried turning off the A/C (which turns on for some reason sometimes in the low 70's), recirc air, auto ventilation, etc. and nothing seems to be working. Looked in the manual and not finding anything that is helping.

We are having the same issue. Car was at the dealer for three weeks. Heater worked for about three days, now it’s doing the same thing. They said they thought the heater Core lines needed bled. But we’re still having issues. Taking it back this Friday.✌🏽. Hope they can fix it.
