I looked online but wasn’t really able to discover what I was searching for, so I’m hoping someone on here could be experiencing a similar problem.
When it’s not pouring or otherwise unpleasant outside, I usually keep the windows and sunroof open while driving in the AC system’s ECON mode (ECON button off). As I was returning from work today, I pressed the button to exit ECON mode because the windows were fogged and the red light wouldn’t go off. The windows simply continued fogging up significantly, so I know the AC compressor is not turning on and is locked in ECON mode. I assumed the light on the button was broken.
As the auxiliary belt tensioner was beginning to make noise, they also had to replace the timing belt when I just got the car back Tuesday afternoon. Is it possible that the AC compressor won’t turn on because the shop failed to reconnect something to it? If so, would the climate control system recognize this and keep the car in ECON mode, or is it more likely a coincidence with the service and an electrical issue?

How can I stop my Audi A4’s AC from running?
The On/Off switch is located on the ECONOMY button. It changes between AC mode and ECON mode after being pressed for about a second. The complete climate control system will switch off if you hold it for around three seconds. Simply press that button, the temp control ****, or the AUTO button once more to switch on.
What is AC ECO for Audi?
The temperature and blower speed can both be changed using the rotary controls. Pressing the buttons will turn on and off the functionalities. When the function is activated, the LED in the relevant button turns on.
In different sections of this manual, the rear window heating link and seat heating link are each discussed.
The temperature should be set to 22 C by pushing the AUTO button (72 F). The air conditioner runs entirely on autopilot and will keep the specified temperature constant. The interior air supply temperature, blower speed, and air dispersion are all automatically controlled. When the heater is turned on, the blower typically doesn’t increase speed until the coolant has warmed up enough (this does not apply to the defrost setting).
When the A/C button is pressed, the air conditioning mode is activated or deactivated. The air is neither cooled nor dehumidified when the air cooling is turned off. As a result, the windows could mist up. When it is cold outdoors, the air conditioning automatically shuts off.
When the AUTO button is pressed, the automated mode is activated. When you use any of the manual air controls, the AUTO mode is instantly turned off. Inside the Audi A3, the automated mode keeps the temperature steady. The output, distribution, and temperature of the air are all automatically controlled. If you briefly hit the AUTO button when automatic mode is engaged, the “eco” mode*1) is triggered. Because the settings react more passively in “eco” mode*, fuel is saved. When eco displays on the console display, the “eco” mode* is active. When you push the AUTO button once again, the “eco” mode* is disabled.
The controls for the driver’s side and the front passenger’s side allow for independent control of the temperature setting. There is a temperature range of +16 C (+60 F) to +28 C (+84 F). The air conditioner display will show LO or HI if it is outside of this range. The temperature is not automatically adjusted at the two extreme settings, when the air conditioner runs continuously at maximum cooling or heating power.
Synchronization: The temperature of the passenger side can be set to match that of the driver’s side by pushing and holding the AUTO button for two seconds. Until the temperature is altered on the passenger side, the settings stay in sync.
To stop the windows from misting up, keep the blower on at a low level. The blower speed can be manually changed. For automated blower speed management, use the AUTO button.
The dispersion of the air can be changed using the buttons, and. To distribute air automatically, press the AUTO button.
Why does my Audi always shut off?
A faulty battery is the primary potential cause of your Audi engine stalling. Usually, when a car won’t start, it’s because the battery is dead. Even with this enormous flag, the automobile battery can still emit warning signals before it entirely fails.
The biggest indicator of a faulty battery is stalling of the engine. Your Audi’s engine stalling because of a faulty battery has a cascading effect. The alternator will have to work harder to keep the engine going if the battery is not fully charged. The engine will experience too much stress as a result of the extra energy the alternator is producing. The engine will stall when you are driving as a result of this tension.
How can the Eco mode on a 2007 Honda Odyssey be turned off?

Does ECON refer to cooling systems?
An energy-saving setting called “Econ mode” functions similarly to a central air conditioner. Once the desired temperature is reached, the room air conditioner will shut off. The fan will then turn on for 20 seconds every 10 minutes to sample the temperature of the air. The compressor will restart if the ambient temperature rises above the predetermined level.
What does my car’s ECON button do?
You must first be aware of what occurs when you hit the Honda ECON button. It’s not magic, and there aren’t any small elves moving cables or tiny gears inside the car. Everything depends on the computer settings in your powerplant. Your engine’s control module adjusts the throttle response, cruise control, air conditioner, and transmission reaction when you press the ECON button to lessen the amount of work your engine has to do. Your powertrain will operate more efficiently the less stress it is under. Who doesn’t want to reduce their petrol expenses?
Can the AC button reduce heat?
To regulate the temperature inside the automobile, use the a/c compressor in conjunction with the heat setting. By doing this, you may dehumidify the air and prevent windows from fogging up. Condensation on windows can be eliminated by turning on the air conditioner.
ECON: What does that mean?
What the ECON button does can be a mystery to you if you’ve never utilized the Honda ECON mode. When activated, the Honda Econ button modifies the settings of a number of various systems, including: At highway speeds, the throttle response is altered to aid lessen acceleration.
Why does my car turn off when I stop moving?
If the issue only sometimes occurs, diagnosing a car that switches off while driving can be challenging. However, the issue with an automobile that has just died after moving is considerably simpler to identify.
- Using an OBD2 scanner, check the engine control unit for any fault codes. In case you receive a problem code, keep running the diagnostics.
- To check the gasoline level and make sure the fuel level gauge is working properly, add 1 gallon (4 liters) of petrol to the tank.
- To ensure a good battery charge, check the battery voltage and attach a car battery charger.
- If your automobile will start after the battery has been charged. While the engine is running, check the voltage using a multimeter. If the voltage is between 13.5 and 14.5 volts, your alternator is working properly. However, if the voltage falls below 13 volts while the car is driving, there is a problem with the alternator system.
- Utilize a fuel pressure gauge to check the engine’s fuel pressure. If not, check the fuel filter and pump. Replace if defective.
- Utilize your diagnostic tool to review live data and search for any unusual engine sensor readings. When starting the engine, see if the crankshaft sensor produces RPM.
- While turning the starter motor on and off, check the RPM meter on your dashboard. The crankshaft position sensor is most likely the issue if it doesn’t move.
Can low oil cause a car to shut off?
The majority of the time, your automobile won’t shut off due to low engine oil. However, if the oil pressure drops too far, the automobile may cut off the engine to protect the driver. Though, newer autos frequently have this.
Can a bad battery cause a car to shut off while driving?
Because the alternator supplies the necessary power, a faulty automobile battery rarely results in the engine cutting out. In some uncommon circumstances, the automobile battery may experience such a short circuit that it will turn off.
Why does my car keep cutting off when I stop?
Your car’s engine is particularly sensitive at idle, which can cause it to shut off after you stop. Numerous factors can contribute to this, but the most common one is a lean fuel mixture that causes the idle to dip too low. This may also be brought on by a bad throttle body.
Why did my car shut off while driving and won’t start?
If your automobile cuts out while you’re traveling and won’t start, the problem is frequently an alternator problem or low fuel pressure brought on by the fuel pump. However, there are numerous potential causes, thus a diagnostic scanner is required to identify them.
Running Out of Fuel
Your car will turn off while you’re driving if it runs out of petrol. You cannot operate the vehicle without fuel. Instead of presuming there is a mechanical issue, it is best to check the fuel. The main causes of this are laziness or an underestimation of the gasoline capacity.
The engine will shut off, and a blocked fuel gauge may even cause it. Keep in mind that a blocked fuel gauge does not give any prior notice. You won’t receive the proper indication, and you risk running out of fuel, which would make driving impossible. Even a frozen gasoline line has been known to cause car accidents.
Dead Car Battery
The car battery, in addition to the fuel, aids in igniting the engine. You can start the combustion process by providing the appropriate power. The battery starts the car even though it does not provide power for it. Other parts of an automobile can be powered by the battery. When the battery can’t charge properly, your automobile will immediately stop. Check to make sure the battery is not dead. Short circuits can occur while you’re driving in addition to your vehicle stopping.
The battery is used by the car when the alternator is malfunctioning. Your car will also die if your car battery is dead. If the alternator is dead, the battery won’t last very long. You can examine the condition of the automobile battery with a multimeter. The battery is not fully charged if it measures less than 12.6V. If the battery voltage falls below 11.7V, it has less than 25% of the charge and needs to be replaced.
Alternator Issues
The alternator keeps the various parts of the car operating efficiently. It is the engine of your car, and if it breaks down, the car will shut off. In order to recharge the battery, the alternator assists in controlling the flow of electricity. Your automobile will cut off while you’re driving if the alternator is damaged. The power supply is where this primarily occurs.
The engine will lose power if the alternator has problems. The alternator will, however, rarely break down. Prior to running into the issue while driving, you must first identify it. The battery will provide electricity if the alternator stops working. Due to the battery’s inability to power the entire car, this can only occur temporarily. After stalling, the car will ultimately turn off.
Faulty Fuel Pump
The engine will need to deliver a consistent fuel supply in order to propel the car. If the fuel supply is compromised, your car will stop while it is in motion. The engine will never receive fuel from the tank thanks to the fuel system. It is the same as not giving the engine any gasoline. For this, it’s crucial to inspect the gasoline pump. It may have an impact on the steady flow of power that fuels the engine.
There is a chance of suffering engine shutoffs when there is a malfunctioning fuel pump. Sometimes, the fuel filter may also be to blame. In most circumstances, the automobile won’t keep turning off, and the fuel supply line itself may result in the same issue. It is advisable to have an expert diagnose the gasoline system.
Electrical Cable Failure
Electrical cable breakdown is another factor that could cause an automobile to turn off while it is being driven. Even more factors, such the alternator and spark plugs, can contribute to a broken electrical cable. The cables are crucial parts that aid in producing enough power. The vehicle will also lose power if it is faulty or loose. The engine can abruptly shut off as a result. Even before it gets to this point, the car may exhibit symptoms like decreased engine performance and poor acceleration. Finding out whether there is an electrical cable failure will be preferable.
Ignition System Problems
When driving, your automobile will switch off if any ignition system component is malfunctioning. For the car to get power, the ignition system is crucial. Numerous issues, including starting, might result from a defective ignition system. Weak combustion from it could cause the automobile to turn off while you’re driving. The issue may be brought on by various factors, such as a worn-out ignition switch or defective ignition relay.
Defective Engine Control Unit
An essential part of the car is the ECU, or engine control unit. It is a little computer task that controls the majority of processes. The ECU monitors the vehicle’s performance and assists in locating any issues. The ability to regulate various engine processes aids in achieving peak engine performance.
However, a malfunctioning automobile computer might cause the engine to lose power. You won’t be able to operate your vehicle if the ECU fails. The car occasionally randomly shuts off before restarting. When the ECU experiences a loss of spark, power, or fuel efficiency, this may occur. The computer’s malfunction might be brought on by a variety of factors. The engine light will let you know if there are any problems.
You must purchase an OBD scanner in order to check the ECU’s functionality. Remember that examining or diagnosing your ECU might be very challenging. The ECU can only be diagnosed by a qualified mechanic using the proper equipment, knowledge, and software.
