Acura TL Window Regulator

Diagnosing Your Acura TL Window Regulator

Opening and closing your windows have become a much more convenient process. Instead of rolling a crank by hand, you can now press a button on your armrest and the window next to you will go up or down, accordingly. What's more, you might even be able to raise and lower your passengers' windows from the controls near the driver's seat. This is all made possible by the motors and regulators found inside the doors of your car. While it's easy to figure out that the motors generate the electrical power that makes the whole opening-and-closing process possible, you might be wondering what your Acura TL's window regulators are for and why they make it impossible to move the window when they malfunction.

Function and suspicious signs of malfunction

Each individual window regulator works to raise and lower your window glass by converting the motor's power into vertical motion. Despite being built to last, constantly opening and closing, one of your TL's windows might wear out this mechanism prematurely. You won't be able to raise or lower this particular window, even if all the other windows are fine. If you do manage to get some movement from this window, it might get stuck halfway. To make sure that it is indeed your Acura TL window regulator that's in need of replacing, you'll need to do a visual inspection to confirm.

Confirming the problem

Instead of buying a replacement product and going through the whole process of changing one of your car parts before finding out that it's another component that's causing the problem, make sure you confirm your suspicions by inspecting your TL.

To do this for your Acura TL window regulator, you need to begin by opening the car's door and removing its panel of the frame. Doing so will expose the window regulator and you'll be able to do a visual and electrical inspection. Check for any frayed cables as well as broken plastic guides and mounting parts, and take note of any parts that need replacing. Afterwards, unhook the wiring harness that connects the window motor to the rest of the car. Then, use these wires to connect the window motor to the positive and negative terminals of your battery. If the motor continues to work, then you should definitely replace your regulator.

  • Servicing Your Acura TL Window Regulators 27 February 2013

    Constantly replacing the different parts of your Acura TL can become extremely expensive. That's why you need to service them regularly. Doing so will ensure that these parts work at their best while lasting for as long as. While it's easy to maintain some of the more visible and accessible parts, your Acura TL window regulators can easily be forgotten until something malfunctions. Instead of waiting for this to happen, you can follow these tips to make sure that the regulators are replaced only when they're old enough to retire:


    Preventing the window regulators from tiring out

    Sometimes, you might find yourself becoming impatient because your windows aren't raising or lowering themselves fast enough. If this happens, don't continue to push the button on your armrest. Otherwise, the regulator and the other window components might tire out, overheat, and ultimately, break.


    Accessing the window regulators

    Each one of your Acura TL regulators can be found behind the door panel of your car. To access them, you'll need to prop the door open before removing the armrest with the help of a screwdriver. Reach through the gap of the armrest and unbolt the panel from the inside with the socket wrench. Then, remove the exterior screws with a screwdriver and clips with a pry bar before removing the panel from the door's frame. Once you've done this, you'll now be able to access your window regulators for maintenance.


    Dusting the window regulators

    Over time, the gears and other components of your window regulators can accumulate dust that will clog and contaminate them. If you leave this unchecked, the dust can eventually cause your window regulators to break. To prevent this from happening, access your regulators and clean them occasionally.


    Greasing the window regulators

    Window regulators need lubrication because they're partly made up of moving metal parts. The lubrication will keep them moving smoothly and freely. To do this, you'll need to remove the regulator from its bolts before cleaning off the old grease and oil with a carburetor cleaner and a paintbrush. Then, use rags to dry the excess cleaner off the regulator before spraying white grease on the front and back of its pivot points and the window motor. You can also use a pipe cleaner to apply grease to the joints, gears, and other small areas. Don't forget to remove the excess grease with a rag before reassembling your power window regulator.
