2003 grand prix gt
upon highway driving last night I noticed cold (ambient) air leaking in through the driver door and into the cabin via the gaps in the window/door lock switch and the door handle. reached behind me and same issue for the rear driver side door. the air flow can be felt many inches from the panel itself; it is fairly significant leakage.
is there a particular seal i should be inspecting for air leakage through the door? upon first inspection of the door, i did not see anything out of the ordinary, and no major seal failures/tears.
