The most common reasons a 2009 Mitsubishi Eclipse 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 2009 Mitsubishi Eclipse 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 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 initial steps to diagnose a non-functioning window in a 2009 Mitsubishi Eclipse?

When faced with a non-functioning window in your 2009 Mitsubishi Eclipse, it's essential to approach the diagnosis methodically. Start by checking the fuse box; a blown window fuse is a common and easily fixable issue that can prevent the window from operating. If the fuse is intact, move on to inspect the window switch for any signs of damage or malfunction, as a faulty switch can disrupt the window's operation. Next, test the window motor to ensure it is receiving power; if the motor is unresponsive, it may need replacement. Additionally, examine the window regulator, as damage here can also lead to window failure. Finally, look for any obstructions or debris in the window track that could hinder movement. By following these steps, you can effectively diagnose the issue and determine the necessary repairs for your vehicle's window.

What are the common problems that could cause the window of a 2009 Mitsubishi Eclipse to not go up or down?

When dealing with a malfunctioning window in a 2009 Mitsubishi Eclipse, 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 it fails, the window may become stuck. Additionally, issues with the power window motor can prevent the window from operating, as a malfunctioning motor will not provide the necessary power for movement. Electrical problems, such as blown fuses or damaged wiring, can also disrupt the window's functionality, making it vital to inspect these components. Another potential issue is a malfunctioning window switch, which may fail to send the correct signals to the motor, resulting in no movement. Furthermore, if the window has come off its track, it may not move smoothly or could become jammed. Lastly, any damage to the window glass itself, like cracks or chips, can hinder its operation. By systematically checking these areas, you can effectively troubleshoot and potentially resolve the window issue in your Mitsubishi Eclipse.

How urgent is it to address the malfunctioning window in a 2009 Mitsubishi Eclipse?

Addressing a malfunctioning window in a 2009 Mitsubishi Eclipse is crucial for several reasons. First and foremost, a window that is stuck open or closed can create significant safety risks, leaving your vehicle vulnerable to theft or environmental elements. Additionally, neglecting this issue can lead to further complications, such as damage to the window regulator or motor, which may result in more expensive repairs down the line. Furthermore, a malfunctioning window can detract from your driving experience, especially during extreme weather conditions, where proper ventilation and comfort are essential. Therefore, it is imperative to prioritize the repair of a malfunctioning window to ensure both your safety and the longevity of your vehicle.
