Ventilation system can't pull in fresh air

I actually have a 2006 Xa, but the ventilation system can't pull in fresh air, and the air that does come in is hot. I have to run the air conditioner almost year round, because if I set the fresh/recirc lever to "Fresh", the air is always hot. Even on cool nights when I roll the windows down, I still have to run the A/C because the incoming air is so hot the car heats up in spite of having the windows rolled down. It needs to be around 40 degrees outside before I can turn off the A/C. When I have "Fresh" air selected, for instance when I'm driving through the mountains, the air smells very stale (i.e. you can't smell mountain air, trees, etc) AND the air coming in is hot. Can you help me?

Open your bonnet (hood) and see if the air intake area is under the bonnet, below the front windscreen and separated from the engine bay by a rubber seal. In my Astra, the air intake area can be seen going from one side of the car to the other, with a rubber seal running along in front of it. When the bonet is closed, it presses down on the seal and is supposed to prevent air coming into the car from the engine bay. It sounds like yours is not doing the job properly - like mine. We coated the seal with talcum powder and closed the bonnet, then opened it to see if the talc had transferred to the under side of the bonnet without any gaps. There was only a small gap, but it was enough to let the heat in from the engine bay. It had driven me crazy for 8 years. I hope this leads you to a solution to your problem.

Does a 2005 Pontiac Sunfire have a PCV valve?

Crankcase Ventilation System Description
A crankcase ventilation system is used to consume crankcase vapors in the combustion process instead of venting them to atmosphere. Fresh air from the intake system is supplied to the crankcase, mixed with blow by gases and then passed through a calibrated orifice into the intake manifold.
The primary control is through the positive crankcase ventilation (PCV) orifice which meters the flow at a rate depending on inlet vacuum. The PCV orifice is an integral part of the camshaft cover. If abnormal operating conditions occur, the system is designed to allow excessive amounts of blow by gases to back flow through the crankcase vent into the intake system to be consumed by normal combustion.

Locate pcv valve.pulled throtle body nothing or valve covers

Crankcase ventilation system is used to consume crankcase vapors created during the combustion process instead of venting them to the atmosphere.
Fresh air is supplied through a filter to the crankcase, the crankcase mixes the fresh air with the blow-by gases and then passed through a positive crankcase ventilation (PCV) orificed tube into the intake manifold.
The PCV orificed tube restricts the flow rate of the blow-by gases using a 3 mm (0.118 in) (a) orifice located at the end of the tube. If abnormal operating conditions arise, the system is designed to allow excessive amounts of blow-by gases to back flow through the crankcase vent tube into the throttle body in order to be consumed by normal combustion.

Why do I have no ventilation in my crank case on my chevy truck

That is what the PCV system is supposed to do. Positive Crankcase Ventilation. The pcv valve (maybe on the valve cover) sucks the fumes out into the intake manifold by a vacuum hose. There is also a fresh air hose to the valve cover from the air breather. As the fumes are sucked out, fresh air is supplied in.
You need to check the pcv system.
