2007 is probably pre diamond logic. It should be the old systems. Like kw9006nz said make sure the evaporator isn't socked full of garbage. It's more than likely under the passenger seat. While under there do yourself the favor or just replacing all the AC and heater components. The blend door actuators, the blower motor, thermostatic switch (this will often cause your problems too), scrape out the old seal foam on the blend door and put new in (hardware stores carry 1 sided sticky window seal foam that works fairly well) these old systems just need to be gone over and refreshed. That or you'll constantly be pulling that seat back up to check and chase the next symptoms.
