The most common reasons a 2012 Toyota Tacoma 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 malfunction or not operate at all.
  • 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 2012 Toyota Tacoma 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.

How urgent is it to fix the non-functioning window in a 2012 Toyota Tacoma?

Fixing a non-functioning window in your 2012 Toyota Tacoma should be treated with a sense of urgency, as neglecting this issue can lead to significant safety and security risks. An open window not only leaves your vehicle vulnerable to theft but also exposes the interior to harsh weather conditions, which can cause damage to upholstery and electronics. Additionally, driving with a malfunctioning window can compromise your comfort, especially during extreme temperatures, making it difficult to maintain a pleasant driving environment. By addressing the problem promptly, you not only enhance your vehicle's security but also protect its interior and ensure a more enjoyable driving experience. Therefore, it is advisable to prioritize this repair to avoid escalating issues that could lead to costly fixes down the line.

What are the steps to diagnose a non-functioning window in a 2012 Toyota Tacoma?

To effectively diagnose a non-functioning window in your 2012 Toyota Tacoma, start with the simplest solutions before moving on to more intricate assessments. Begin by checking the window lock switch on the driver's door to ensure it is not activated, as this can prevent other windows from operating. If the switch is fine, proceed to inspect the window motor and regulator by removing the door panel, looking for any visible signs of damage or wear. It's also essential to check the vehicle's fuse box for any blown fuses that could disrupt the window's electrical system. If the battery has recently been replaced or disconnected, this may require you to hold the switch manually to operate the windows fully. As you test the window operation, pay attention to any unusual behavior, such as the window only moving halfway or exhibiting slow movement, which could indicate motor issues. By following this structured approach, you can efficiently identify the root cause of the problem and determine the necessary repairs for your Tacoma's window system.

What are the common problems that could cause the window in a 2012 Toyota Tacoma to stop working?

When troubleshooting window issues in a 2012 Toyota Tacoma, it's essential to consider several common problems that could be at play. One of the first areas to check is the electrical system, as a blown fuse or a faulty relay can easily disrupt window functionality. If the electrical components are functioning correctly, the next step is to inspect the window motor, which is known to fail over time and can prevent the window from moving. Additionally, the window regulator is another critical component that may malfunction, leading to a complete window failure. Wiring issues, including frayed or damaged wires, can also impede the window's operation, as can problems with the window switch itself. For those experiencing issues specifically with the rear windows, it’s worth checking the lockout switch, which may inadvertently disable window operation. Lastly, be mindful of corrosion in the switch, particularly if the vehicle has been exposed to moisture, as this can cause intermittent functionality or restrict movement to one direction. By systematically examining these potential issues, DIYers can effectively diagnose and resolve window problems in their Tacoma.
