Are you dealing with frustrating issues related to your 2019 Ram’s Active Grill Shutters? You’re not alone! This guide will help you navigate these common problems and offer practical solutions. We’ll cover:

Stay tuned to get your 2019 Ram running smoothly again.

The Role of Active Grill Shutters in 2019 Ram

Active Grill Shutters (AGS) are more than just a fancy addition to your 2019 Ram. They play an integral role in improving vehicle performance in several ways. Let’s delve into the specifics.


Why It Matters

Aerodynamics is crucial for any vehicle as it directly affects speed and fuel consumption. Active Grill Shutters help by reducing air resistance, allowing the vehicle to glide more smoothly on the road.

How AGS Helps

When the shutters are closed, they streamline airflow around the vehicle instead of letting it enter the engine compartment. This simple mechanism can significantly improve aerodynamic efficiency.

Fuel Efficiency

Why It Matters

In today’s world, who wouldn’t want to save on fuel costs? AGS can help you do just that by improving the vehicle’s aerodynamics, which we’ve already discussed.

How AGS Helps

Reduced air resistance means less effort is needed to propel the vehicle forward, leading to lower fuel consumption. Over time, this can add up to significant savings.

Engine Cooling

Why It Matters

A hot engine is not just inefficient but can also lead to long-term damage. AGS plays a pivotal role in regulating engine temperature.

How AGS Helps

The shutters open when the engine needs cooling, allowing air to flow into the engine compartment. When the engine is cool, the shutters close, improving aerodynamics and fuel efficiency.

Common Problems with 2019 Ram Active Grill Shutters

If you own a 2019 Ram, you might have faced or heard about issues with its Active Grill Shutters (AGS). While AGS serves essential roles in your vehicle, problems can arise. Let’s get right into the common challenges and how to fix them.

Grille Shutters Stuck in Open or Closed Position


Dirt and debris can accumulate on the shutters, causing them to get stuck. Another cause could be a malfunctioning actuator, the part responsible for moving the shutters.


  1. Manual Cleaning:
    • Use a soft-bristle toothbrush and a degreaser to gently scrub away dirt and debris from the shutters and their hinges.
  2. Actuator Replacement:
    • If the actuator is malfunctioning, it’s best to replace it. Disconnect the battery, remove the old actuator, and install the new one. Make sure to follow the manufacturer’s guidelines.

Grille Shutters Fail to Open or Close Properly


Faulty wiring or sensor issues can prevent the shutters from operating correctly. Damaged wires and connections are often the culprits.


  1. Wiring Inspection:
    • Turn off the engine and inspect the wiring near the grille shutters. Look for frayed or disconnected wires and repair or replace them as needed.
  2. Sensor Checks:
    • Use an OBD-II scanner to check for sensor errors. If the scanner indicates a problem, a sensor replacement is typically necessary.

Grille Shutters Making Noise During Operation


Unusual noises are generally a sign of wear and tear on the moving parts or insufficient lubrication.


  1. Lubrication:
    • Apply a silicone-based lubricant to all moving parts, making sure to reach the hinges and corners.
  2. Part Replacement:
    • If lubrication doesn’t solve the issue, identify the worn-out parts and replace them. You might need to consult a mechanic for this.

Grille Shutters Leaking Water into the Engine Compartment


Weather seals around the shutters can deteriorate over time, allowing water to seep in.


  1. Weather Seal Inspection:
    • Examine the weather seals around the shutters for wear and tear or gaps.
  2. Sealant Application:
    • If the weather seals are damaged, applying a silicone sealant can be a quick fix. For a more permanent solution, replace the weather seals.

Engine Running Hotter Due to Grille Shutters


If your engine is running hot, it might be because the shutters are not opening when they should, hindering airflow into the engine compartment.


  1. Thermostat Check:
    • A faulty thermostat can cause the engine to overheat. Replace it if it’s not functioning correctly.
  2. Cooling System Service:
    • If the cooling system is clogged or leaking, a complete service may be required. This usually involves flushing the system and replacing the coolant.

Decrease in Fuel Economy Due to Grille Shutters


If the shutters are not closing properly, your vehicle will experience increased air resistance, negatively impacting fuel economy.


  1. Shutter Inspection:
    • Ensure the shutters close properly. If they don’t, the increased air resistance can affect fuel economy.
  2. Professional Diagnosis:
    • If a simple visual inspection doesn’t reveal any issues, it might be best to have a mechanic perform a thorough examination.

Prevention Tips for 2019 Ram Active Grill Shutter Issues

Prevention is better than cure, and this is especially true for mechanical components like Active Grill Shutters in your 2019 Ram. Here’s how you can minimize the risk of running into common problems.

Cleaning and Maintenance

How Often

Regular cleaning is key. Aim to clean the grille shutters at least once a month or more frequently if you drive in dusty or muddy conditions.

Recommended Products

  • Use a gentle degreaser to clean the shutters.
  • Soft-bristle toothbrushes are effective for reaching tight spots.
  • Silicone-based lubricants are ideal for keeping the moving parts smooth.

Wiring and Electrical Checks

How Often

Wiring should be inspected every three to six months, especially if you frequently drive in harsh weather conditions.

What to Look For

  • Frayed or exposed wires
  • Loose or disconnected wires
  • Signs of corrosion on the connectors

Sensor and Actuator Checks

How Often

Perform these checks at least twice a year, or whenever you experience issues with the shutters operating incorrectly.

What to Look For

  • Unusual noises from the actuator
  • Error messages on your OBD-II scanner related to sensors

Cooling System Maintenance

How Often

Your cooling system should be serviced at least once a year or as recommended by the vehicle’s manufacturer.

What to Do

  • Flush the cooling system to remove debris and old coolant.
  • Replace with new coolant as per manufacturer specifications.
  • Inspect the radiator, hoses, and clamps for any wear and tear.


So there you have it! Keeping your 2019 Ram’s Active Grill Shutters in tip-top shape is easier than you think. From regular cleaning to routine checks, a little upkeep goes a long way. Follow our guide to dodge those pesky problems and keep your ride smooth and efficient. Happy driving!
