Try it with the window down and see if it's better.

Those doors are light and they push a lot of air. The relief valves in the cab cant' vent the air fast enough, particularly with a regular cab (that's why a Suburban can be better - because it's got more internal room to compress the air).

Mine got much worse after I replaced the door seals. I usually keep my door open while the passenger closes his/her door, then close mine after them.

You can take the Pressure Relief Valves our of the bottom of the doors and that will sometimes help; the tradeoff is you will get a bit of cold air through them during the winter.
