Just curious if anyone else notices that it seems to take forever for the outside (cooler air) to get circulated into the cockpit? It seems that my car will blow warm air if I shut off my car and park it for 10-15 minutes. If I turn on the AC it's really ice cold right away and as soon as I switch back to turning the AC off it seems warm like the heat is on. Very weird.

You are drawing "fresh" air from the hot engine bay. Switch to recirculate to avoid the hot air.
