The most common reasons a 2021 Hyundai Tucson window won't go up or down are window's electrical system such as a fuse or relay, a broken window motor, or a broken window regulator.
  • Fuse, Relay or Electrical System: A blown fuse or a faulty relay can disrupt the electrical circuit, causing components to fail or operate intermittently.
  • Window Motor: A faulty window motor or a broken window regulator can prevent the window from moving up or down properly.
  • Window Regulator: A faulty window regulator can cause the window to become stuck or operate erratically due to worn gears or a broken cable.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2021 Hyundai Tucson window won't go up or down?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

If the door window motor fails, the window may not open or close, or it may operate intermittently. Traditionally, problems with power windows were caused by faulty switches or electrical wiring - especially the wires running between the door and the vehicle body that are subjected to repeated flexing. In these cases, the window might operate intermittently when the door is opened and closed. While this may still be the case on newer cars, it is increasingly common to find window motor problems that originate with a control module. Still, the switches and wiring should be checked thoroughly before replacing a window motor.

If one of the windows in a vehicle will not open or close properly, a failing door window regulator might be the cause. A window that is moving intermittently, or one that gets stuck on the way up or down, could also indicate a broken regulator. Other symptoms might include a clicking, chattering, or grinding noise when the window moves. In some cases a severely damaged window regulator could cause the window to drop inside the door.

When a switch can not make contact and close the circuit, the window cannot be raised and lowered. If the switch on the driver's door will not raise or lower the window in question, but the switch on the corresponding door works just fine, this is a good indication that there is a switch failure. This works the other way around, as well. If the switch on the door does not cause the window to function, but the driver's switch does, that is an indication of a passenger door window switch failure.

Due to the nature of electrical systems on modern vehicles, the range of problems these can cause are nearly limitless. However, there is a way to categorize them in two ways. Permanent and intermittent problems. Permanent problems appear and remain. This may be the vehicle will not start, the radio does not work, or the door chime will not turn off among many, many others. These problems are more straight-forward to diagnose since they present themselves at all time. This means there will always be a fault to find. Intermittent electrical problems, however, can be difficult or impossible to locate, since they appear then disappear without warning. The best case scenario for an intermittent issue is when replicating the problem is easily accomplished and understood. This allows a technician to make an issue semi-permanent, allowing them to find the fault. Other issues that come and go without warning and cannot be replicated on demand must occur when the technician is servicing the vehicle, otherwise there is no problem to correct. It is most important to understand that electrical system faults always require inspection, and can include the vehicle working in any manner, or not working at all.

Like we noted in the last section, general diagnosis symptoms are the most vague of the bunch. There are several diagnostic spectrums, electrical diagnosis, drivability diagnostics, engine diagnostics, transmission diagnostics, and the list could continue for about 5 or 10 more spectrums of diagnostics. The most important take-away here, is that general diagnostics are diagnostics that have no other spectrum in which they fit, or the problem is unknown. This means that any vehicle left outside of a repair facility with the keys and an authorization to perform diagnosis will be diagnosed under the general diagnosis spectrum.

What steps should I take to diagnose the power window issue in my 2021 Hyundai Tucson?

To effectively diagnose the power window issue in your 2021 Hyundai Tucson, start with a systematic approach that prioritizes simpler solutions before delving into more complex diagnostics. Begin by checking the fuse associated with the power windows, as a blown fuse is a common and easily fixable problem. If the fuse is intact, proceed to test the power window switch to ensure it is functioning correctly, as a faulty switch can also disrupt window operation. Next, inspect the wiring connected to the power window motor for any signs of damage or loose connections, as these issues can prevent the windows from working. If the wiring appears intact, use a multimeter to test the power window motor for proper power and ground signals; if the motor is not receiving power, it may need replacement. Finally, assess the window regulator, which is crucial for the movement of the window. If all these components check out and the issue persists, it may be time to consult a professional mechanic or an authorized Hyundai service center for further assistance. By following this diagnostic approach, you can efficiently identify and address the power window issue in your vehicle.

What are the common problems that could cause the window in a 2021 Hyundai Tucson to stop functioning?

When dealing with a non-functioning window in a 2021 Hyundai Tucson, it's essential to understand the common problems that may be at play. One of the primary culprits is a faulty window regulator, which is responsible for the mechanical movement of the window and can wear out over time, leading to operational failures. Additionally, issues with the power window motor can prevent the window from responding to switch commands, rendering it immobile. Electrical problems, such as blown fuses or damaged wiring, can also disrupt window functionality, making it crucial to inspect the fuse box and wiring connections. Another potential issue is a malfunctioning window switch; if pressing the switch yields no movement, it may need replacement. Furthermore, the window can sometimes come off its track, causing it to get stuck or move unevenly, which may require realignment. Lastly, any visible damage to the window glass itself, such as cracks or chips, can impede movement and should be inspected. By understanding these common problems, DIYers can effectively troubleshoot and resolve window issues in their Hyundai Tucson.

How urgent is it to repair the malfunctioning window in my 2021 Hyundai Tucson?

When it comes to repairing a malfunctioning window in your 2021 Hyundai Tucson, urgency cannot be overstated. A window that fails to close properly not only compromises your safety by obstructing visibility but also exposes your vehicle to potential theft and environmental damage. Rain, snow, or debris can easily enter through an open window, leading to costly interior repairs and discomfort during your drives. Moreover, a malfunctioning window can significantly diminish your vehicle's resale value, as prospective buyers are likely to be deterred by visible maintenance issues. Additionally, in some jurisdictions, driving with a faulty window may violate local laws, resulting in fines or penalties. Therefore, addressing this issue promptly is crucial to ensure your vehicle remains secure, comfortable, and compliant with regulations, ultimately safeguarding your investment and peace of mind.
