air conditioning
my air conditioning will not blow out anything it has power but will not blow i have replaced the control panel and when i turn it on there is some kind of clicking and popping by the vent above the radio and on the passengers side
My car has 142000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello there, thank you for asking about your 2008 Ford Mustang. The popping sound is from the electronic blend door actuator failing and not being able to control the air direction. You should have the actuator removed above the gas pedal on the evaporator case. Once the actuator is removed, manually move the blend door to make sure it moves freely. If it is fine, then replace the actuator and retest. If you would like help, a certified technician from YourMechanic can inspect why your AC is not working.

It is the job of the AC actuator to control the opening and closing of the airflow in response to the thermostat, thus controlling air movement and allowing cool air to blow down the ducts and into the house.
The blend door actuator is typically located closer to the heater core and evaporator than the mode door. Mode Door Actuator: The mode door actuator controls which vent(s) air blows through.
The most common symptom of the A/C Actuator going bad or when the Blend Door is stuck is when you feel inconsistent air flow coming in. The desired air you want whether it be hot or cold, is being diverted incorrectly, so you are not getting a consistent temperature out of the A/C system.
Temperature Blend Air Door Actuators: The temperature blend air door actuator controls the temperature of the air flowing from the vents by mixing hot and cold air from the heater core and the evaporator.
Actuator failure – signs and symptoms
Complete loss of power, causing the vehicle to enter limp mode. Intermittent low pressure. Low boost. Overboost.
Typically, vehicles have 3 or 4 actuators. Vehicles with rear controlled HVAC will often have additional actuators to control the auxiliary unit, bringing the total per vehicle to as many as 6. DID YOU KNOW?
This product is an electronic hammer intended to move the workpiece (object to be moved) by applying a striking force to the workpiece by rapidly elongating a piezoelectric actuator. It can be applied to uses such as the fine position adjustment of a temporarily assembled part or rotation centering.
An actuator is a part of a device or machine that helps it to achieve physical movements by converting energy, often electrical, air, or hydraulic, into mechanical force. Simply put, it is the component in any machine that enables movement.

Changes from cooling to the heating season can cause your actuators to start making odd noises. Often this is attributed to lower relative humidity levels and drying environments.

Air conditioning is blowing hot air – car stalls when A/C is on
ANSWER : In order to diagnose all the different problems you have, I having the A/C pressures checked to see if the system is low on refrigerant from a leaking compressor or another component. The rough idle may be due to a dirty throttle body and idle control system. If you would like to have this checked for you, a certified professional from YourMechanic can come to your car’s location to inspect the A/C and rough idle in order to proceed with the proper repairs.

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

My 2003 Hyundai air conditioning works fine but often starts blowing hot air, especially when idling.
ANSWER : Hi There,
It sounds like you may have a condenser fan that may not be cooling the AC condenser properly. As you may know, the job of the AC condenser fan is to cool down the AC condenser as it generates a lot of heat during the course of its primary function, which is to convert the AC gas refrigerant into a liquid form, a process that generates a significant amount of heat. As the AC condenser fan blows cool air across the condenser, this allows the condenser to remain cool, keeping the pressure down in the AC system which helps to generate cooler air. I would suggest having a professional from YourMechanic come to your location to take a look at your vehicle.

air conditioner not blowing air from dash vents, but blowing air from side vents
ANSWER : A few different items can cause the air to not blow out of the dash vents. The most common are a blend door or a control switch. The best method for the AC diagnosis feature can be found in the vehicles owners manual. I recommend having your AC checked by a qualified technician, such as one from YourMechanic, to have the problem diagnosed and repaired correctly.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

Air conditioning doesn’t work – 1988 Jeep Grand Wagoneer
ANSWER : Check the fuse for the heater/AC blower motor. If the fuse is good, then either the blower motor resistor or the blower motor itself is suspect. The blower motor resistor provides for multiple speeds for the blower motor. A professional mechanic, like YourMechanic, can diagnose and replace the failing component.

Air conditioning blowing mildly cold air on the coldest setting, turned off/on again, now blowing cold air, should it be checked?
ANSWER : If you are getting ready for a long trip and suspect the cooling fan may be not coming on for the radiator and a/c then you should have the a/c and cooling system performanced checked before trip. Nothing worse than breaking down when out of town in a strange area.

Air conditioning smells bad when car enables autostop feature
ANSWER : Your vehicle is new enough that I couldn’t find much information on the air conditioning system. I’m guessing your vehicle probably has a dual scroll AC compressor in which one scroll is driven off the engine and the other is electric. In order to prevent lack of cooling at idle, this design is used in hybrids and vehicle with start/stop ability. So, the lack of cooling may be due to a problem with this system. The foul smell by be result of bacteria accumulating on the AC components. Replacing the cabin filter may help with this problem somewhat. I suggest you have a trained professional diagnose your vehicle firsthand to determine the exact cause of the smell.
