The most common reasons a 1999 Acura SLX 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 1999 Acura SLX 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 steps to diagnose a non-functioning window in a 1999 Acura SLX?

When diagnosing a non-functioning window in a 1999 Acura SLX, it's crucial to follow a structured diagnostic approach that emphasizes simpler fixes before tackling more complex issues. Start by checking the fuse related to the window; a blown fuse is a common culprit that can easily be replaced. If the fuse is operational, the next step is to test the window switch to ensure it is delivering power to the window motor. A faulty switch may need to be replaced to restore functionality. Following this, inspect the wiring that connects the switch to the motor for any signs of damage or loose connections, as these can impede power flow. If the wiring checks out, proceed to test the window motor itself to verify it is receiving power when the switch is activated; if it isn’t functioning, replacement may be necessary. Finally, consider the condition of the window tracks; cleaning and lubricating them can often resolve issues caused by debris or insufficient lubrication. By systematically addressing these areas, you can effectively diagnose and resolve the issue with the window in your Acura SLX.

What are the common problems that could cause the windows to stop functioning in a 1999 Acura SLX?

When dealing with window malfunctions in a 1999 Acura SLX, it's essential to consider several common problems that could be at play. One frequent culprit is a faulty speed sensor, which can disrupt the electrical signals necessary for window operation. Additionally, low brake fluid levels can affect the vehicle's overall electrical system, potentially leading to window issues. In more severe cases, total brake failure may occur, which can also impact the functionality of various electronic components, including the windows. While these problems can sometimes be diagnosed and addressed through DIY methods, it is crucial to approach the situation with caution. If the issue persists or if you're unsure about the diagnosis, consulting a professional mechanic is advisable to ensure a thorough and accurate resolution.

How urgent is it to repair the malfunctioning window in a 1999 Acura SLX?

When it comes to repairing a malfunctioning window in your 1999 Acura SLX, urgency is key. A malfunctioning window can create significant safety concerns, particularly in emergency situations where quick access to exit the vehicle is crucial. Additionally, a window that does not operate properly can expose you to harsh weather conditions, compromising your comfort and the integrity of your vehicle's interior. Security is another critical factor; a broken window can make your car an easy target for theft, putting your belongings at risk. Moreover, neglecting the repair can lead to further damage within the window system, which may escalate repair costs and complicate the issue. Lastly, in many regions, functional windows are not just a matter of convenience but also a legal requirement for road safety and vehicle inspections. Therefore, addressing the malfunction promptly is essential to ensure your vehicle remains safe, secure, and compliant with regulations.
