In order for the system to continuously control the temperature inside the vehicle, a number of sensors are used to gauge how hot or cool the air is. The information from the sensors is then used to determine how much warm or cool air needs to be pumped into the vehicle to maintain the temperature desired by the users.
Pick a regular, comfortable temperature setting, similar to the temperature of your thermostat at home. Then simply press AUTO. The system will automatically figure out how to get to that preferred temperature most quickly.
The blower motor is responsible for sending air through the vents of your car. Over time, blower motors can become damaged, or completely fail. In which case, air will no longer come out of your vents.
The cold side of the air conditioner blows cool air over the chilled coils and filters it into the room you`re living in. The warm side of the air conditioner uses an expansion valve in taking whatever hot air might be inside your home and filtering it outdoors.
Despite the fact that cool air is what we typically associate with air conditioning, a car`s air conditioning system also controls heat. Turn the temperature and fan setting dials clockwise to use the AC system for heat, or, if you have a digital display, just push the increase temperature button to turn on the fan.
Climate control consistently monitors the temperature in the car and then heats or cools the cabin space accordingly, whereas air-con is more of a manual system where you have to tell it what to do. You set the temperature and fan speed, and then the air con will stay on those settings until you adjust them yourself.
In Summary. We recommend setting your thermostat to AUTO for the best balance of energy efficiency and comfort. If you are concerned about indoor air quality or suffer from allergies, the ON setting`s increased air filtration could be beneficial.
A manual air conditioning system stays on at the cooling and blower setting you select and keeps on blowing at that pace until you switch it lower. Climatronic, on the other hand, automatically keeps your vehicle at a specific temperature you select.
The recirculation mode is comparatively better. But, if you use it for long, the air inside will become impure. So, during long journeys, you can switch to the fresh air mode once in a while to let fresh air in.
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling.
Most people know that turning up the thermostat on their air conditioner to a higher temperature will result in cooler air blowing from the vents. However, there is a point at which increasing the temperature any further does not make the air cooler – it just uses more energy and costs more money.
Automatic Climate Control is an air conditioning system that maintains the manually pre-set interior temperature of your car at the desired level.
The system is designed to adjust the fan speed, air flow distribution and delivered air temperature to quickly and efficiently reach and keep the interior of your vehicle at the temperature you set.
There are two fundamental types of temperature control; open loop and closed loop control.
Climate control uses air conditioning to automatically adapt to and regulate your desired cabin temperature. This system allows for much more automation and is generally controlled using your vehicle`s infotainment/multimedia system.
Air conditioning, often abbreviated as A/C (US), AC (US), or air con (UK), is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as “comfort cooling”) and in some cases also strictly controlling the humidity of internal air.
The most common air conditioning systems include window air conditioners, portable air conditioners, wall hung split or multi head split systems, and ducted air conditioners. There is a wide variation in the quality and features of each air conditioner, even within its own class.
There are benefits to having your air conditioner set to “auto” and “on.” The benefits of the “auto” setting include higher efficiency, lower energy bills, better humidity control, less wear and tear on some components, and quieter running.
Why you should normally set your thermostat to AUTO. Compared to the ON setting, the AUTO setting gives you benefits such as: Lower energy consumption. In AUTO mode, the blower fan only runs when necessary, which cuts down your AC system`s energy usage.
Leaving your air conditioner on is actually more efficient than frequently turning it on and off. Having your AC on also allows you to better control humidity in your home throughout the day. The lower the humidity in a home, the more comfortable it feels during hot weather.
The thermostat sensor is located near the evaporator coils. These coils are inside your air conditioner unit. As the air is sucked through the return vents, the air passes by the sensor and the coils. As the air passes the sensor, it reads the temperature and compares that reading to the setting on your thermostat.
Cars with A/C systems do not have a second thermostat controlling the temperature of the air inside the car. A/C systems use refrigerant and air compressors to cool the outside air down before it enters your car.

I just replaced the front passenger window regulator and motor and it works but only when i am using the rear passenger switch
ANSWER : Your Audi uses a window control module to operate the windows. The switches send a command to the module, and the module sends the power to the window motors. I’ve seen the modules do some screwy things, especially when the battery voltage gets low, but I wouldn’t run out and buy a module just yet. It may be possible to communicate with it with the right software and there might be some re-set that can be done. If you contact Your Mechanic, they can send a technician to your home or office to check out your spooky windows and tell you whether you need a new module or something else.

How do I use the passenger temperature controls?
ANSWER : The passenger side temperature can be controlled independent of the driver’s side. To set the passenger temperature, use the Passenger Temperature Control buttons. Press the + button to increase the temperature, or press the – button to decrease the temperature.

What do the controls do on the dual automatic temperature control system?
ANSWER : If your car is equipped with a dual automatic temperature control system, it allows you to set a different temperature for the driver side and passenger side. Once you’ve set the temperature, the system will automatically maintain it until you change a setting. Here’s how the controls work:

Auto Driver Side: This activates the automatic temperature control system for the driver. If the passenger side is not on auto and programmed separately, it will have the same temp as the driver side. The system automatically controls most aspects to keep the car at the preset temp, including:

Fan speed
Temperature
Vent selection
Fresh or recirculated air
A/C on and off
Heating

Rear Defrost: Push this button to turn on the rear glass defroster.
Front Defrost: Push this to turn on the front defroster.
Defrost and Lower Vents: This turns on both the front defrost and the lower vents at your feet.
Power: This turns the system on and off. Turning it right and left adjusts the fan speed manually, as well.

Upper Vent: Push this to choose upper vent operation only.

Split Vent: Push this to direct air from both the upper and lower vents.
Lower Vents: Push this to have air directed only out of the lower vents.
Auto Passenger Side: Sets the temperature desired for the passenger side. If this is not set, the passenger side will default to the same temp as the driver side.
Heated Seats: You have two heated seat buttons (one for each front seat). Push them to turn the heated seats on or off.
Recirculated Air: Push this to change from fresh air to recirculated air and back again.
Max A/C: Turns on maximum air conditioning.
A/C: Turns on the normal air conditioning.
Outside Temp: This readout tells you what the temperature is outside the vehicle.

Why is my air system blowing out hot air in spurts and why is the temperature gauge nearing hot while in use?
ANSWER : This can be caused for a variety of reasons such as a malfunctioning thermostat, a radiator not flowing properly, a faulty coolant temp sensor or AC refrigerant not properly being supplied to the AC compressor. Your car’s AC system puts a heavy strain on your car’s engine when it runs as it requires a lot of power to run. When the AC compressor comes on it puts additional strain on the motor that may be already struggling to stay cool as a result of any of the issues named above. I would recommend having an expert from YourMechanic come to your home to diagnose and repair.

How do I use the temperature control?
ANSWER : The temperature control knob is located in the climate control cluster, on the center console. The knob controls how hot or cold the air coming out of your vents is. If you turn the knob counter-clockwise, the air will get colder; if you turn it clockwise, the air will get hotter. The knob is color-coded (blue for cold, red for hot) to help you remember this.

The climatic control is on one temperature all the time hot on drivers side cooler on passanger side the flap control moter for ho
ANSWER : A temp sensor malfunction could be causing your problem. If the controller is getting bad information, it’s going to operate the doors according to that information. So a sensor replacement is indicated. However, these systems can also have problems with the stepper motors themselves that drive the flaps. All the little plastic gears can get jammed up. In most cases, the self diagnostics will catch that and give you a code, but not always. If you have the right scan tool, you should be able to activate the motors and watch them work. Working on the climate control can be difficult and time consuming, if you want to have the job taken care of for you, contact YourMechanic and they’ll send a technician to your home or office to diagnose your climate control issues and advise you as to what to do about it.

How do I use the driver temperature controls?
ANSWER : To adjust the temperature, use the Driver Temperature Control buttons. Press the + button to increase the temperature, or press the – button to decrease the temperature. If the dual zone temperature setting is turned on, then these buttons will control the driver side temperature. If the dual zone setting is turned off, then these buttons will control the temperature of the entire car.

ABS, ESP, EBR malfunction
ANSWER : You’re getting into an area that is kind of a dark art when you’re getting these kinds of codes. While I don’t know any of the symptoms that the car is exhibiting, I can tell you that failure in one of the control units can lead to codes showing up in the others and the ABS, ESP is a likely culprit since it interprets the wheel speed signals and sends the information to the other modules. You’re right that the module has to be coded, and I don’t think that Snap On has the software for that so the only place to go is the Star Diagnostic. (The consumer version of the Mercedes SDS ) You can Contact YourMechanic and see if anyone in your area has the appropriate equipment for this. Otherwise, this may be a case that would best be consigned to the Mercedes Dealer.
