Experienced mechanics share their insights in answering this question :
The AC compressor is responsible for compressing the refrigerant in your air conditioning system. By compressing the refrigerant it increases the pressure that is in the air conditioning lines. When the pressure is increased there is more room for the pressure to decrease. A decrease from high pressure to low pressure will also cause a decrease in temperature. This is how the air-conditioning system works. If you need help with this issue, consider YourMechanic, as one of our mobile technicians can diagnose your A/C firsthand and help you fix it accordingly.
How to Identify and Fix Common car Problems ?

Knocking or clicking usually signals loose mounting bolts or any of the other various air conditioning components not being tight enough. The loose parts will rattle and shake and you`ll hear a racket when you kick on the AC. To troubleshoot this issue, turn your engine on, pop open the hood, and crank up the AC.
Clicking: Damaged or malfunctioning controls and relays can cause a clicking noise at the compressor as these components try but fail to function. Ticking, rattling, clicking or rumbling: A loose piece of hardware could cause sounds like this to occur near the compressor.
If the compressor is turning on and off fairly quickly then that means that there is still a pressure issue. It can be caused by low refrigerant or high pressure. It can also be caused by a bad A/C pressure switch. Any of these will cause this to occur.
Banging: When banging noises are coming from your compressor, there may be a loose or damaged connecting rod, crankshaft, or piston pin inside that`s causing the issue. Clanking: Loose or unbalanced compressor parts can also create a clanking noise, which may escalate to loud banging when left untreated.
This is usually due to your AC`s relay turning your AC on and off. If that clicking is loud and/or continues for more than a few seconds, you probably have an issue with a broken relay or a worn wire in your thermostat. Contact a professional technician to identify and fix the problem.
Generally, a noisy actuator does not indicate an actual problem. It is caused by the friction between the urethane belt and the nickel plated pulley surfaces as they rub together during engagement causing a squeak just like your new sneaks on a gym floor .

My 2003 ford explorer wont start up just get click click click click click click click click
ANSWER : If the battery is weak and the voltage is dropping to below 9 volts you will get the clicking without the starter turning the motor. Have the battery voltage checked and if battery cannot hold a load then replace it and clean the battery terminals and recheck system to see if it starts.
when I turn my ac on my cars idle drop and stalls out and the ac is hot
ANSWER : Hello, thank you for writing in. Although the pulley is still spinning, the compressor has likely failed. If it is not properly regulating pressure in the system, one of the first signs is a warm air conditioner. Considering yours is not cooling off, the pressures are not correct. If you believe the compressor is working correctly, you may want to check for a clogged line before replacing it. Keep in mind, a blocked line has likely put extra strain on the compressor, and may cause premature failure. For more help with testing or replacing the compressor, contact our service department to schedule an appointment.
2011 chevy impala makes clicking sound when i turn on the AC. Clicking will continue even after car is turned off, and does not st
ANSWER : Hi, what you’re describing is a fairly common issue with Chevrolet and GM products. It’s most likely the actuator motor for the blend door in the A/C ducts behind the dashboard, especially if the noise seems to originate from somewhere behind the dashboard.
The connectors for the actuator tend to corrode and cause resistance that results in a bad signal to the control for the actuator. The control then continues to drive the motor, which can result in broken teeth in the actuator/blend door’s plastic gears.
There are probably two actuators, one behind the glovebox and one on the driver’s side. If it’s not the actuators themselves, it could be a relay, but the service history of Chevrolets suggests the actuators.
If you need assistance with this, feel free to schedule an appointment with YourMechanic to diagnose the noise you’re hearing firsthand and replace your Impala’s A/C actuators and blend doors as necessary.
When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Why is my car heater blowing cold air? I start my car, give it a few minutes and the heater never heats up.
ANSWER : The lack of heat being generated by your system may indicate a clogged heater core. The [heater core]((https://www.yourmechanic.com/services/heater-is-not-working-inspection) is a small radiator like unit that circulates the hot coolant from the engine through the heater core which then uses this warm coolant to heat the inside of the car with the help of the blower motor that blows the warm air through the vents inside the car. The other possibility is that the thermostat may not be allowing the engine to reach a normal operating temperature and since the engine’s warm coolant is the essential source of the heater core supplying heat to the inside of the vehicle, this can impact the warmth of the heat inside the vehicle. I would suggest having an expert from YourMechanic come to your location to diagnose your heating system.
10 loud clicks every 10 min from the AC and Heater Control panel area.
ANSWER : What you may be hearing is the a/c temperature or mode door actuators clicking when they get to one end of their travel of the door they control. This is not normal and you should try to isolate the noise to what actuator is causing the noise and then have it replaced.
Low coolant light comes on when AC, defrost or heater is on, but only if the car is in gear and stopped, what’s wrong with my car?
ANSWER : First, you want to make sure your cooling system is full. Check the radiator not the coolant jug. And check it when it is cold. If it needs coolant, add some. Of course, I don’t feel this problem is an actual low coolant condition. I would expect to find an electrical failure in the instrument cluster or from a component or wiring harness that is connected to the instrument cluster.
As a technician, I have access to reports from technicians across the country. I could not find any reports of this problem, so diagnosing this will require an experienced tech as this is not a common problem. In addition, this happens at intermittent times making it difficult to recreate. The most challenging part of this diagnosis will be recreating the symptom. I suspect it has something to do with the brake switch circuitry because it only seems to happen when you have your foot on the brake. I would begin my diagnosis there with a wiring diagram and test light in hand. The brake switch, instrument cluster, and environmental controls all interact with each other. Something is crossed either because of a failed module or damaged wiring in a harness.
Aside from making sure the coolant is full, this will not likely leave you on the side of the road. If you take it in to be diagnosed, be prepared for them to spend more time than usual to figure it out. Since it isn’t a key problem, you may need to live with it until it completely fails making it much easier to diagnose. Either way, I do recommend having a certified mechanic diagnose the warning light to make sure there isn’t anything serious going on.
Good luck.
