There may be vacuum hoses that operate your valves or they may be cables that manually operate the valves.
You are looking for a valve that switches your air vents and also a valve that diverts some of your heated radiator fluid to your heater core.
Look for a broken cable or a small vacuum hose that has cracked or has become disconnected.
