Understanding the Subaru Power Window Motor

The power window motor is essential to your Subaru Forester’s power window system. It provides the necessary force to move the window up and down smoothly. If you’re experiencing issues with your power windows, it could be due to a faulty power window motor.

To understand how the Subaru power window motor works, it’s essential to know its basic components first. The motor consists of a small electric DC motor, a gear mechanism, and a linkage connecting the motor to the glass. When you press the button or switch to operate your window, an electrical current flows through wires connected to the motor, causing it to spin and turn gears that ultimately move the glass up or down.

One common issue with power window motors is wear and tear over time. Due to constant use, the gears can become worn out or damaged, resulting in difficulty in moving the windows. This can also happen if debris or dirt gets inside the gears and causes them to jam.

Another potential cause for malfunctioning power windows is a faulty regulator. The regulator works with the motor by controlling how much force is applied when moving the window up or down. A broken regulator can result in jerky movements or even complete failure of your windows to move at all.

Symptoms of a Faulty Subaru Forester Power Window Problem

The Subaru Forester is known for its reliability and performance, but like any other vehicle, it may experience problems over time. One of the most common issues faced by Subaru Forester owners is a faulty power window motor. This can be frustrating, especially when you’re stuck with a window that won’t roll up or down. This section will discuss the symptoms of a faulty Subaru Forester power window problem to help you diagnose and address the issue.

1. Unresponsive Power Windows:

The first and most obvious symptom of a faulty power window motor is when your windows don’t respond to the switch or button. If you press the button to roll down your window and nothing happens, there’s likely an issue with your power window motor.

2. Slow Movement:

Another sign of a failing power window motor is slow movement or jerky motion when trying to roll up or down your windows. This could indicate that the motor struggles to work properly and needs attention.

3. Window Gets Stuck:

If your windows get stuck in one position and won’t move, it indicates something is wrong with your power window system. This could be due to a damaged motor or a malfunctioning regulator.

4. Strange Noises:

A healthy power window should operate smoothly without making any noise. So, if you hear grinding, clicking, or scraping sounds while operating your windows, it could mean an issue with the motor gears or possibly debris interfering with its movement.

Diagnosing the Power Window Motor issues

When diagnosing power window motor issues in your Subaru Forester, there are a few key things to keep in mind. The power window motor is an essential component of your vehicle’s window system, responsible for powering the movement of the windows up and down. If you notice any problems with your power windows not functioning correctly, it could be due to a malfunctioning power window motor.

The first step in diagnosing power window motor issues is to check the fuse. A blown fuse can often be the culprit behind non-functioning power windows. Locate the fuse box in your Forester and check the diagram on the cover or owner’s manual to find the corresponding fuse for the power windows. If the fuse needs replacement, this may solve your issue.

If replacing the fuse does not fix your problem, then it is time to check for other potential causes, such as faulty wiring or a malfunctioning switch. Inspect all wiring connections related to your Forester’s window system and make sure they are securely connected. Additionally, try using both switches (driver side and passenger side) for each window to see if either switch works, indicating a potential issue with one specific switch.

Another essential aspect to consider when diagnosing power window motor issues is listening for unusual sounds when operating your windows. If you hear grinding or clicking noises when attempting to roll up or down your windows, it could indicate a worn-out motor that needs replacement.

Testing the Subaru Forester Electric Window Motor

The electric window motor is essential to your Subaru Forester’s power windows. It is responsible for the smooth operation of the windows, allowing you to easily open and close them with just a push of a button. However, like any other mechanical part, it can experience wear and tear over time and may require replacement.

If you notice that your power windows are not functioning correctly or have completely stopped working, it could be due to a faulty electric window motor. In this section, we will guide you through testing the Subaru electric window motor to determine if it needs to be replaced.

Before starting the testing process, ensure all fuses related to the power windows are intact. If any fuse is blown, replace it and see if the issue is resolved. If not, then proceed with testing the Subaru Forester electric window motor.

Step 1: Check for Power Supply

The first step in testing your Subaru Forester’s electric window motor is to check for a proper power supply. Using a multimeter set at DC voltage, touch its positive probe on the red wire connected to the motor while grounding its damaging investigation on the vehicle’s chassis or frame. There might be an issue with the wiring or electrical system if there is no voltage reading or it shows less than 12 volts.

Step 2: Test Motor Continuity

Next, a multimeter set in resistance (ohms) mode is used to check for continuity across both terminals of the electric window motor. A reading of zero indicates good continuity, while an infinite reading means that there is an open circuit in the motor’s windings.

Step 3: Check Motor Operation

To test if your Subaru Forester’s electric window motor is operating correctly without removing it from its housing, connect jumper wires directly from a 12-volt battery to each terminal on the motor connector plug. The polarity does not matter, as reversing these connections will only change the direction of rotation. If the motor does not operate, it is most likely faulty and must be replaced.
