Heat Inside The Car

I’ve had my XPT only a few weeks and the weather has been moderate and only a little bit cool so far. What I’ve noticed is that when the fan comes on I feel quite a bit of heat in the car and has me concerned about how this wil be in July and August. I’m not sure where or how the heat is entering but it is very noticeable. I have full doors, roof and windshield so I’m sure that plays in to the situation some. Is this normal and if so, any suggestions to help keep it out?

TIA!
