Blower motor

[Big Daddy]

So, I've just noticed that when I start my truck with the heat on, the blower motor will start running. Run for about 1 min then shut off. In about 5 min, after that it kicks back on and runs fine. This happens every start up no matter what the engine temp. What the heck would cause this?

I'm having a very similar issue with my truck too.

my 2020 does that sometimes, until i get in and push the start button. However, i've noticed during some cold mornings, when i remote start it, the "defrost" button is lit. I'm not sure if this is a built-in in feature or not. But, during the summer, if i remote start, the fan is on "HI" until i hit the start button. Maybe to get rid of heat in the truck?

anyway, no complaints here
