The most common reasons a 2015 Jeep Wrangler 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 Jeep Wrangler 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 are the steps to diagnose a non-functioning window in a 2015 Jeep Wrangler?

When diagnosing a non-functioning window in a 2015 Jeep Wrangler, it's essential to adopt a systematic approach that begins with the simplest solutions before moving on to more complex issues. Start by checking the window switch, as a malfunctioning switch is often the easiest fix. If the switch appears to be operational, proceed to inspect the fuse box for any blown fuses related to the window system; replacing a blown fuse can quickly resolve the problem. Next, test the window motor using a multimeter to ensure it is receiving power; if not, the issue may lie in the wiring or the motor itself. Following this, examine the window regulator for any signs of damage, as a faulty regulator can hinder window movement. Additionally, inspect the wiring connected to both the window motor and switch for any loose connections or damage that could disrupt functionality. If these steps do not lead to a resolution, it may be prudent to consult a professional mechanic who specializes in automotive electrical systems, as they can provide expert insight and solutions. By following this diagnostic approach, you can effectively identify and address the issue with your Jeep's window.

What are the common problems that could cause the window in a 2015 Jeep Wrangler to not go up or down?

When dealing with a window that won't go up or down in a 2015 Jeep Wrangler, it's essential to understand the common problems that could be at play. One of the primary culprits is a faulty window regulator, which is crucial for the window's movement. If this component is damaged, it can hinder the window's operation entirely. Additionally, the power window motor may be experiencing issues; if this motor is worn out or defective, it won't provide the necessary power for the window to function smoothly. Electrical problems can also be a significant factor, such as a blown fuse or a malfunctioning switch, which can disrupt the power supply to the window system. Furthermore, a malfunctioning window switch itself can prevent the window from responding to commands. Lastly, alignment issues can cause the window to become off track, leading to operational difficulties. By identifying and addressing these common problems, you can effectively troubleshoot the window issue in your Jeep Wrangler and potentially restore its functionality.

How urgent is it to repair the malfunctioning window in my 2015 Jeep Wrangler?

When it comes to repairing a malfunctioning window in your 2015 Jeep Wrangler, the urgency of the repair cannot be overstated. A malfunctioning window can significantly compromise your vehicle's safety and security. For instance, if the window is stuck in a partially open position, it not only exposes your vehicle to theft but also allows the elements to wreak havoc on your interior. In adverse weather conditions, such as rain or snow, water can easily enter the cabin, leading to potential damage that could be costly to repair. Furthermore, a window that is completely stuck closed can hinder proper ventilation, making your driving experience uncomfortable, especially during hot weather. Addressing these issues promptly is crucial, as neglecting them can lead to further damage to the window mechanism, ultimately increasing repair costs. Therefore, it is advisable to prioritize the repair of your Jeep's window to maintain both safety and functionality, ensuring a secure and comfortable driving experience.
