The most common reasons a Jeep Comanche 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 Jeep Comanche 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.

Troubleshooting Window Issues in a Jeep Comanche

When troubleshooting window issues in your Jeep Comanche, it's essential to adopt a methodical diagnostic approach. Begin by inspecting the fuse and relay associated with the window system, as these are often the simplest components to check and can easily be replaced if faulty. Next, assess the electrical system to ensure there are no broader issues affecting power delivery. If the electrical components are functioning correctly, turn your attention to the window motor; a malfunctioning motor can prevent the window from operating altogether. If the motor appears to be in good condition, the next step is to examine the window regulator, which may require lubrication to ensure smooth operation. Applying a lubricant like WD-40 can often resolve sluggish movement. Additionally, inspect the wiring connections for any signs of damage or looseness, as these can disrupt the window's functionality. Finally, test the window switch; if pressing against the glass helps the window move, this could indicate a problem with the switch itself. By following this structured approach, you can effectively diagnose and address window issues in your Jeep Comanche, ensuring a smoother and more reliable driving experience.

What to Check When Your Jeep Comanche Window Won't Go Up or Down?

When faced with a Jeep Comanche window that won't go up or down, it's essential to systematically diagnose the problem to identify the root cause. Start by examining the electrical system, as issues with the fuse or relay can disrupt window functionality. If the electrical components are intact, turn your attention to the window motor; a malfunctioning motor is a frequent culprit behind window operation failures. Additionally, inspect the window regulator, as a faulty regulator can hinder the window's movement. Don't overlook the window switch, which can also malfunction and prevent the window from responding. If the window has gone down but refuses to come back up, a simple cleaning of the master switch with isopropyl alcohol may restore its function. To ensure smooth operation, lubricate the window tracks and cables with appropriate lubricants like White lithium spray grease or dry graphite spray lube. Lastly, if the window stops working at either the fully up or down position, consider disassembling the regulator and flipping the spiral cable around before reassembling it, as this can sometimes resolve the issue. By following these troubleshooting steps, you can effectively address the common problems associated with your Jeep Comanche window.

Why is it Urgent to Fix a Stuck Window in a Jeep Comanche?

Fixing a stuck window in a Jeep Comanche is not just a matter of convenience; it is a pressing issue that requires immediate attention. A stuck window can lead to serious complications, especially during inclement weather, where rain can infiltrate the vehicle, causing damage to the interior and creating an uncomfortable environment for passengers. Moreover, a malfunctioning window can compromise the safety and security of the vehicle, leaving it vulnerable to theft or unwanted entry. Ignoring this problem can exacerbate the situation, potentially damaging critical components such as the window motor, switches, and wiring, which could result in costly repairs down the line. By addressing the issue promptly, you not only enhance the driving experience by ensuring proper visibility and ventilation but also mitigate the risk of further complications that could arise from a neglected window. Therefore, it is essential for Jeep Comanche owners to prioritize fixing a stuck window to maintain the vehicle's functionality and ensure the safety of all occupants.
