Blower motor runs when car is running

Hi,

Just acquired the car listed above LS model from the original owner.
Car has digital climate control.

Blower motor runs whenever key is on, and also when car is running.

Climate control is off, not on automatic.

Heat and A/C work fine.

I would say the speed on the blower motor is approximately at medium, considering the sound it makes.

Car has 40,000 miles.

Thank you in advance for your assistance.
