Hey guys! Is your 2017 GMC Sierra's screen acting up? Don't worry, you're not alone! Many Sierra owners face issues with their infotainment screens, and luckily, it's often fixable. This guide will walk you through everything you need to know about replacing the screen, from identifying the problem to finding the right replacement and getting it installed. Let's dive in!

Identifying the Problem

Before you jump into replacing the screen, it's crucial to accurately diagnose the issue. Accurately diagnosing the issue will save you time, money, and a whole lot of frustration. Common problems with the 2017 GMC Sierra screen include:

• Blank Screen: This is perhaps the most obvious issue. The screen is completely black and unresponsive. It could be a simple power issue, a faulty screen, or a problem with the head unit itself.
• Cracked or Damaged Screen: Physical damage is easy to spot. Cracks, scratches, or shattered glass can render the screen unusable.
• Touchscreen Unresponsive: The screen lights up, but the touch functionality doesn't work. This can be due to a faulty digitizer (the touch-sensitive layer), software glitches, or connection problems.
• Flickering or Distorted Image: The screen displays a distorted image, flickers, or shows lines. This could indicate a problem with the screen's internal components or the video signal.
• Screen Freezing or Lagging: The screen freezes intermittently or responds very slowly to touch inputs. This might be a software issue, but it can also be a sign of hardware problems.

To properly diagnose the problem, start by checking the basics. Make sure the vehicle is running and that the radio is turned on. Try adjusting the screen brightness and contrast settings. If the screen is completely blank, check the fuses related to the radio and infotainment system. Consult your owner's manual for the fuse locations. If the screen is only partially malfunctioning, try performing a system reset. This can often resolve minor software glitches. To reset the system, look for a small reset button on the radio or infotainment unit. If there is no reset button, disconnect the negative battery cable for a few minutes, then reconnect it. This will often reset the entire system.

If you've tried these basic troubleshooting steps and the problem persists, it's likely that you need to replace the screen or, in some cases, the entire head unit. Before proceeding, it's a good idea to consult with a qualified mechanic or car audio specialist. They can perform a more thorough diagnosis and recommend the best course of action. Keep in mind that some screen issues may be covered under warranty, so check your vehicle's warranty coverage before spending any money on repairs.

Finding the Right Replacement Screen

Okay, so you've determined that you need a new screen. Now, the hunt begins! Finding the right replacement screen is key to ensuring compatibility and proper functionality. There are a few options here, each with its pros and cons:

• OEM (Original Equipment Manufacturer) Screen: This is the exact same screen that came with your Sierra from the factory. It guarantees perfect compatibility and the same level of quality as the original. However, OEM screens are usually the most expensive option. You can purchase them from your local GMC dealer or from online retailers that specialize in OEM parts.
• Aftermarket Screen: These screens are made by third-party manufacturers. They can be a more affordable alternative to OEM screens. However, quality can vary greatly, so it's important to do your research and choose a reputable brand. Look for aftermarket screens that are specifically designed for the 2017 GMC Sierra to ensure proper fit and functionality. Read reviews and check the manufacturer's warranty before making a purchase.
• Used Screen: You can sometimes find used screens from salvage yards or online marketplaces. This is the cheapest option, but it's also the riskiest. There's no guarantee that the used screen will be in good working condition, and you may not be able to return it if it's defective. If you decide to go this route, inspect the screen carefully for any signs of damage before buying it.

When choosing a replacement screen, make sure it's compatible with your specific model and trim level of the 2017 GMC Sierra. The screen size and resolution should match the original screen. Also, consider the features of the screen. Some aftermarket screens may offer additional features, such as higher resolution, brighter display, or improved touch sensitivity. Finally, check the warranty of the replacement screen. A good warranty will protect you against defects and malfunctions.

To ensure you get the right screen, have your vehicle's VIN (Vehicle Identification Number) handy when you're shopping. This will allow the seller to verify compatibility. Also, be sure to compare prices from different vendors before making a purchase. Don't be afraid to ask questions and negotiate for a better deal.

The Replacement Process

Alright, you've got your replacement screen! Now comes the exciting part: the replacement process. You have two main options here:

• DIY (Do It Yourself): If you're comfortable working on cars and have some basic tools, you can attempt to replace the screen yourself. There are plenty of online tutorials and videos that can guide you through the process. However, be warned that this can be a challenging task, and you could damage your vehicle if you're not careful.
• Professional Installation: If you're not confident in your DIY skills, it's best to have a professional install the screen for you. This will ensure that the job is done correctly and that your vehicle is not damaged. You can take your Sierra to a local mechanic, car audio shop, or GMC dealer for installation.

If you choose the DIY route, here's a general overview of the steps involved:

1. Gather Your Tools: You'll need a set of screwdrivers, plastic trim tools, a socket set, and possibly a multimeter.
2. Disconnect the Battery: This is crucial to prevent electrical shocks and damage to your vehicle's electrical system.
3. Remove the Trim: Use the plastic trim tools to carefully remove the trim pieces around the radio and infotainment unit. Be gentle to avoid breaking the clips.
4. Remove the Radio/Infotainment Unit: Unscrew the bolts that secure the radio or infotainment unit to the dashboard. Carefully pull the unit out of the dashboard.
5. Disconnect the Wiring Harnesses: Disconnect all of the wiring harnesses from the back of the radio or infotainment unit. Be sure to label each harness so you can reconnect them correctly later.
6. Remove the Old Screen: Depending on the model, the screen may be held in place by screws or clips. Remove the screws or carefully pry the screen out of the unit.
7. Install the New Screen: Connect the wiring harness to the new screen. Carefully position the new screen in the unit and secure it with screws or clips.
8. Reconnect the Wiring Harnesses: Reconnect all of the wiring harnesses to the back of the radio or infotainment unit.
9. Reinstall the Radio/Infotainment Unit: Carefully slide the unit back into the dashboard and secure it with the bolts.
10. Reinstall the Trim: Snap the trim pieces back into place.
11. Reconnect the Battery: Reconnect the negative battery cable.
12. Test the New Screen: Turn on the vehicle and test the new screen to make sure it's working properly.

If you're having a professional install the screen, be sure to get a quote beforehand. The cost of installation can vary depending on the shop and the complexity of the job. Also, ask about the warranty on the installation. A good shop will guarantee their work and offer a warranty on the installation.

Post-Replacement Checks and Maintenance

Congrats! Your new screen is installed. Post-replacement checks and maintenance are essential to ensure everything is running smoothly. Here are a few things to check after replacing the screen:

• Functionality: Test all of the features of the new screen, including the touchscreen, radio, navigation, and any other apps or functions. Make sure everything is working properly.
• Calibration: Some screens may require calibration after installation. Follow the manufacturer's instructions to calibrate the screen for optimal performance.
• Software Updates: Check for any available software updates for the radio or infotainment system. These updates can often improve performance and fix bugs.
• Screen Protection: Consider applying a screen protector to the new screen to prevent scratches and damage.
• Cleaning: Clean the screen regularly with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the screen.

To keep your new screen in good condition, avoid exposing it to extreme temperatures or direct sunlight for extended periods of time. These conditions can damage the screen and shorten its lifespan. Also, be careful not to drop or bump the screen, as this can cause cracks or other damage. If you notice any problems with the new screen, such as flickering, distortion, or unresponsiveness, contact a qualified mechanic or car audio specialist for assistance.

By following these tips, you can ensure that your new screen provides years of reliable service.
