2013-2015 Acura ILX Front Window Regulator and Motor Guide

Symptoms of a Failing Window Regulator

When the window regulator in a 2013-2015 Acura ILX begins to fail, the signs are usually obvious. Ignoring them can lead to a window that is stuck open or falls into the door. Be aware of the following symptoms:

• Grinding, Clicking, or Scraping Noises: This is the most common sign of failure. It often means the internal cable has frayed or broken, or the plastic gears have been stripped. Stop using the window immediately if you hear these sounds to prevent further damage.
• Slow or Jerky Window Movement: If the window moves slower than it used to, or if it stutters on its way up or down, the motor could be straining due to resistance from a failing regulator.
• Window Drops or Won't Stay Up: A broken regulator can no longer support the weight of the glass, causing the window to slide down on its own, either partially or all the way into the door. This presents a significant security risk.
• Crooked Window: If the glass tilts forward or backward as it moves, it means one of the regulator's lift points has broken or the glass has come off its track.
• Window is Stuck: The window may refuse to move at all, even if you can hear the motor trying to work. This often happens after a loud pop or snap, which is the sound of the cable breaking.

Known Issues, TSBs, and Recalls

While there are no specific recalls or Technical Service Bulletins (TSBs) from Acura directly addressing a widespread defect with the window regulators on the 2013-2015 ILX, some related issues are worth noting:

• Auto-Up/Down Reset: A common issue reported by owners is the auto-up function failing, where the window goes all the way up and then immediately comes back down a few inches. This is often a problem with the system's memory, not the regulator itself. It indicates the pinch protection feature is being falsely triggered. This typically requires a reset procedure after a battery disconnect or part replacement.
• Noises: Forum discussions mention various noises, including wind noise, which can sometimes be traced back to improper window sealing or alignment after a repair.
• Recalls: The 2013-2015 ILX has been subject to other recalls, including for corroding driveshafts (Safety Recall 21-018) and Takata airbag inflators (Safety Recall 16-010), but none for the window regulators.

Buying a Used 2013-2015 ILX Window Regulator

A used OEM window regulator can be a reliable and cost-effective alternative to expensive new parts or lower-quality aftermarket units. Here’s what to look for when buying a recycled part.

Part Number Verification

It is critical to get the correct part for your vehicle's side and year range. The front regulators for the 2013-2015 ILX are different from the 2016+ models. The parts are also specific to the driver's and passenger's side.

The 'A11' suffix generally indicates a later revision of the part, but it is interchangeable with the 'A01' version for this vehicle generation. Always confirm the part number before purchasing.

Physical Inspection Checklist

When inspecting a used regulator assembly, check the following:

• Cables: Ensure the cables are tight and not frayed, kinked, or popping out of their tracks. This is the most common failure point.
• Plastic Components: Look for any cracks or stress marks on the plastic pulleys and glass mounting brackets.
• Motor: Check that the electrical connector and pins are clean and free of corrosion.
• Frame: Inspect the metal frame for any signs of bending or significant rust that could impede its movement.

Replacement Overview

Replacing the front window regulator is a manageable DIY job for someone with basic mechanical skills. The process involves removing the interior door panel to access the regulator assembly.

• Difficulty: 3/5
• Estimated Time: 1.5 - 2.5 hours
• Tools Needed: Phillips screwdriver, flathead screwdriver (for prying), panel clip removal tool, 10mm socket and ratchet.

Key Replacement Steps

1. Disconnect the car battery.
2. Carefully remove the interior door panel by removing screws and using a trim tool to release the clips.
3. Peel back the plastic vapor barrier to expose the inside of the door.
4. Temporarily reconnect the window switch to lower the window until you can see the bolts holding the glass to the regulator.
5. Unbolt the glass from the regulator and carefully lift it out of the door, or tape it securely in the full 'up' position.
6. Disconnect the motor's electrical connector.
7. Unbolt the regulator assembly from the door frame and remove it.
8. Installation is the reverse of removal.

Power Window Reset Procedure

While the exact procedure can vary slightly, the general process for most Honda and Acura vehicles is as follows:

1. Turn the ignition to ON (II).
2. Using the switch on the door you just repaired, press and hold the switch down until the window is fully open, and continue holding it for 2-5 seconds.
3. Pull and hold the switch up until the window is fully closed, and continue holding it for 2-5 seconds.
4. Test the auto-up/down function. If it doesn't work, repeat the process.
