Are these related to each other? When I push my truck beyond 3000rpm, which happens when I'm towing my 5th wheel on inclines, the a/c stops blowing cold and stops removing humidity. Typically I can turn off the ignition, remove the key, open a door, and then restart it, and the a/c is back on. But not every time.
