    I have a 2000 Jeep Grand Cherokee Limited V8 and I’m hearing a clicking/turning noise from the dash and in the console where the heat/ac is. I’m not sure exactly where it is coming from but if someone could tell me what the problem maybe please let me know! Thank you.

    RE: t could be the noise of an actuator turning, or a door inside the heater case moving. A cable could be rubbing on something as it moves, too. Without actually hearing it or being able to take a look, your best bet is to get up under the dash and listen while you change modes of the heat/air conditiong, etc and listen for it to happen or feel around for where it is coming from.

    Sounds like one of the heater and air conditioning system door motor actuators is noisy. These actuators move the different doors in the dash depending on how you set the HVAC system. There is one for the temperature door that switches from hot cold. Another motor controls what is called the motor door – which controls where the airflow comes from – vent, floor, defroster. Play with the A/C heater controls little bit changing the temperature and the airflow position to see if the noise changes. That would give an indication as to which motor is noisy. Normally they make noise because they cannot find the correct position that the HVAC control head wants to put it in. You could try disconnecting the battery for a few minutes, then reconnecting, then starting the truck and let it run for a few minutes before you touch any of the controls to see if maybe it will reset itself.

    Turn the temperature control and the blend controls to see which one is making the noise. That will help to figure out which one is noisy.
