The blend door controls the heat/AC, depending on which you want. It is located in the heater box behind the dash. If you want heat, it opens to allow air to blow threw the heater core, it you want AC, it closes that door, and allows the air to blow threw the evaporator in the AC system. If it's not opening and closing properly, you won't have heat or AC, depending on how it's stuck.....RR
