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.
