The most common reasons a 2015 Toyota Highlander 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 2015 Toyota Highlander 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 issue with the windows not functioning in my 2015 Toyota Highlander?

When diagnosing the issue with the windows not functioning in your 2015 Toyota Highlander, it's essential to adopt a systematic approach that begins with the simplest solutions before progressing to more complex diagnostics. Start by checking the basics, such as ensuring that the child safety lock is disengaged, as this can prevent window operation from the driver's controls. If that checks out, proceed to reset the window system, which is a common fix for many Toyota models. This involves turning the ignition to the "on" position, rolling down each window fully while holding the switch down for five seconds, and then rolling them back up in the same manner. If the windows still do not respond, inspect for electrical issues, especially if the problem arose after a battery change or electrical surge, as this may require reinitializing the window settings. Next, assess the window motors and regulators; if individual switches work but the master control does not, the issue may lie with the master switch or a relay. If a window remains unresponsive, replacing the motor or regulator might be necessary, which involves removing the door panel. Additionally, consider environmental factors like high humidity, which can affect window functionality. If these steps do not resolve the issue, consulting diagnostic resources such as instructional videos or forums can provide further insights tailored to your vehicle model. Following this structured approach will help you effectively diagnose and potentially resolve the window issues in your Highlander.

What are the common problems that could cause the windows of a 2015 Toyota Highlander to stop functioning?

When dealing with power window issues in a 2015 Toyota Highlander, it's essential to understand the common problems that may arise. Electrical problems are often at the forefront, where damaged or disconnected wires can disrupt the flow of power to the window motor. Additionally, the window switch, particularly the master control switch located in the driver's door, can wear out over time, necessitating a replacement if it fails to respond. Another frequent issue is the disconnection of the regulator arm from the window glass, which prevents movement and requires reattachment to restore functionality. In some cases, the window motor itself may burn out, leading to a more complex repair that involves accessing the door panel for replacement. It's also worth noting that after a battery change or electrical surge, the windows may need to be reinitialized by rolling them down and up while holding the switch. Environmental factors, such as extreme heat or humidity, can temporarily affect window operation, but these issues typically resolve with changes in conditions. Lastly, ensure that the child safety switch is not engaged, as this can block window operation from the driver's controls. By identifying and addressing these common problems, you can effectively troubleshoot and restore the power windows in your Highlander.

How urgent is it to address the issue of the windows not functioning in a 2015 Toyota Highlander?

Addressing the issue of non-functioning power windows in a 2015 Toyota Highlander is crucial, especially when considering the potential safety risks and damage that can arise from neglecting this problem. If the windows are stuck in the down position, the vehicle becomes vulnerable to theft, vandalism, and exposure to harsh weather conditions, which can lead to significant interior damage and electrical issues. Moreover, the inconvenience of having to manually operate the windows can disrupt daily activities and diminish the overall driving experience. While some issues may be resolved through simple re-initialization, persistent problems often indicate deeper electrical or mechanical failures that require professional attention. Therefore, it is essential to prioritize the repair of non-functioning windows not only to ensure the vehicle's security and comfort but also to prevent further complications that could arise from prolonged neglect.
