cool air in a 2538 cab?

[DarkHelmet]

Does anyone have an idea on how to get cool fresh air into the cab without using the A/C when it's not warm out? If I keep the A/C off and the fresh air vents open, or closed, I end up just getting hot air into the cab no matter what the temperature is outside. Is there some trick to making this work? Don't see a reason why I'd kick on the A/C when the temp is 70.

It sucks that they didn't make a way to vent air through the cab. If you open the back window you don't get any flow at all because there's no way for the air to get in.

You are in a fish bowl,just run the A/C.Run mine at 65 F.

If the sun is shining and 70 degrees, it’s going to get warm in there without the A/C on.
You can usually take the doors off a tractor without much hassle.

I've run the a/c when the outside temps are in the 30's because if you didn't it would roast you out. I don't know if the smaller cab of a 2538 heats up quite like the large cabs on Case/IH Magnum MX series or not.
