The air from the ac will not enter the car, only the heater air. I hear a continuous clicking noise when the car is on. The heater air is always on and won't turn off but sometimes if I hit a bump it will go off and the ac will kick in. But when I touch the ac compressor line it is cold. I wanted to check the ac & heater blend(vent) door but I don't have my manual to show me a diagram where to locate it. Can you please help me?
