Active Grill Shutters are components that are located behind the front grille of a vehicle. They help to reduce wind noise and drag on the car by automatically opening and closing depending on engine temperature, speed, and air flow. Common problems with Active Grill Shutters include them not working at all or becoming stuck in either open or closed positions.
This may be due to a faulty relay switch, broken wiring/connections, worn out actuators/motors (which control the shutters), or a malfunctioning electronic control module. Fixing these issues usually involves replacing any damaged parts as well as resetting electrical connections and calibrating them according to manufacturer instructions.
Active grill shutters are an increasingly popular feature on many modern vehicles, but they can be prone to problems. Common issues include sticking open shutters, which can reduce fuel efficiency and increase engine noise, or stuck-closed shutters that interfere with the vehicle’s cooling system. If your active grille shutter isn’t working properly it is important to have it investigated by a qualified technician right away in order to avoid any further damage.

Can Active Grill Shutter Cause Problems?
Yes, active grill shutters can cause problems. They are designed to open and close when needed in order to regulate the amount of air that enters the engine’s intake system and help improve fuel economy. However, if they malfunction or become stuck in one position, it can create a vacuum leak which results in a decrease in power and acceleration as well as an increase in emissions.
In addition, this type of shutter can also be damaged by debris such as leaves or rocks that get caught up inside them and prevent them from opening or closing properly. If you notice any issues with your vehicle’s performance after having an active grill shutter installed then you should take it into a certified mechanic for inspection right away to ensure everything is functioning correctly.
How Much Does It Cost to Fix Active Grill Shutters?
The cost to repair active grill shutters can vary greatly depending on the specific problem. If the issue is a broken or damaged shutter, then a replacement part may be necessary, which could range in price from $50 to several hundred dollars. If there’s an issue with the motor that powers the shutter, then labor costs will also come into play and could add another few hundred dollars in expense.
In some cases, it may even require replacing both parts of the system if they’re no longer working together properly. Additionally, some cars have multiple active grille shutters so you may need more than one replacement part or motor as well as pay for additional labor time for installation. Ultimately, it’s best to consult your local mechanic about their rates and what needs to be done before estimating how much it might cost you to fix your vehicle’s active grill shutters.
How Do You Test an Active Grille Shutter?
Testing an active grille shutter is essential to ensure that it is functioning properly and able to provide the desired aerodynamic performance. The first step when testing an active grille shutter is to check for proper operation of the actuator, which controls the opening and closing of the grille shutters. This can be done by performing a visual inspection or using specialized diagnostic tools such as multimeters or oscilloscopes.
Once this has been done, then you need to assess how well the actual movement of each individual shutter blade works with regards to its angle, speed and position relative to other blades in order for it to achieve optimal performance from wind tunnel tests. To do this you will use high-speed cameras or laser scanning devices in order measure these factors accurately. Additionally, static pressure measurements are also taken from within the vehicle’s ducting system in order to verify air flow volumes through each individual shutter blade at different speeds and angles of attack during dynamic driving conditions on road surfaces.
Is the Active Grill Shutter Important?
The active grill shutter is an important component of any modern vehicle. It helps to reduce drag and improve fuel efficiency by closing off the front grille when it’s not necessary for engine cooling. This helps to decrease the amount of air entering the engine, making it more efficient and ensuring that a greater percentage of fuel energy is converted into power rather than lost in wind resistance.
In addition, the active grill shutter also reduces aerodynamic noise from outside sources, providing you with a quieter ride overall. With all these benefits, it’s clear why having an active grill shutter installed in your car or truck is so important – not only does it save money on gas and make your drive smoother but also increases safety as well.
At What Speed Range is Active Grille Shutter Generally Closed?
Active grille shutters are a great way to improve aerodynamics, reduce drag and increase fuel efficiency in vehicles. Generally speaking, these shutters close when a vehicle reaches speeds of around 30 mph or higher. At this speed range, the air flow over the front end of the vehicle is strong enough that it forces the shutter blades closed.
This helps to reduce turbulence and drag on the front end of the car which in turn improves fuel economy. Additionally, at lower speeds such as city driving where there isn’t much wind resistance, active grille shutters can remain open allowing more air into an engine’s radiator while simultaneously reducing cooling system requirements by up to 25%. In conclusion, active grille shutters generally close when a vehicle reaches speeds of around 30 mph or higher which allows for improved aerodynamic performance and reduced drag on cars as well as better fuel economy without sacrificing engine cooling capabilities.
Can I Remove Active Grill Shutter?
Removing an active grill shutter (AGS) from your vehicle can be a tricky process depending on the make and model of your car. In general, you should consult with a professional mechanic in order to get the job done properly. It is important to remember that AGSs are designed to improve fuel efficiency by closing off part of the area under the hood when not needed for cooling, so it’s possible that removing one without expert assistance could actually reduce your vehicle’s performance rather than improving it.
Additionally, removing an AGS requires accessing components such as brackets and screws which may require specialized tools or knowledge. Therefore, if you plan on attempting to remove an AGS yourself, please be sure to read up on all relevant safety information before doing so and understand what any potential risks might be associated with performing this task yourself.

Active Grille Shutter Check Engine Light
The active grille shutter check engine light typically indicates a malfunction with the vehicle’s air intake system. The active grille shutters are designed to open and close while driving in order to allow more or less air into the engine, depending on speed and other factors. If these shutters become stuck in one position, it can throw off the balance of airflow going into the vehicle’s engine, which will then cause an increase in emissions as well as decrease fuel economy.
This will result in your check engine light illuminating due to this issue.
Active Grille Shutter Repair Cost
The cost of repairing an active grille shutter can vary depending on the make and model of your vehicle, as well as the extent of the damage. Generally speaking, you should expect to pay between $200-$400 for a professional repair job that includes replacing any damaged parts. If you’re considering doing this repair yourself, be sure to buy all necessary replacement components from an authorized dealer in order to ensure proper fitment and quality.
Can You Drive With a Bad Active Grill Shutter
It is not recommended to drive with a bad active grill shutter. This component helps reduce air resistance and drag from the front of your vehicle, as it opens and closes depending on the speed you are driving at. If your active grill shutter is damaged or failing, this can affect the aerodynamics of your car and lead to reduced fuel efficiency.
Additionally, if it becomes jammed in an open position, debris can be drawn into the engine which could cause serious damage. If you suspect that there may be an issue with your active grill shutter it is best to have it inspected by a qualified mechanic who will advise you on what repairs need to be made.
