Window regulator defect Window regulator replacement costs 3 E1643449107625

Is a window regulator repair pending? For example, because one of the window regulators in the vehicle only works sporadically or not at all? We have the information about the costs and the process. Yes, for the time being some important information about the window regulator at a glance. Today's window regulators are built to raise and lower heavy loads. Due to the high load is the most common deficiency a broken cable or a disc holder, which canceled is. It also happens that the electronics of the engine are defective or that wiring harnesses cause problems. Because the frequent opening and closing of the vehicle door often leads to cable breaks.

This is how the defect is recognized!

  • the vehicle window only moves up and down more slowly
  • creaking or cracking (or grinding / grinding) noises when operating the window regulator
  • the power window button is pressed, but the window does not move
  • the window opens or closes sporadically by itself

If one of the defects occurs and it is ignored or noticed too late, the window regulator motor can be damaged and burn out, for example. Of course, this should be avoided. A workshop should therefore be contacted as soon as possible as soon as one of the symptoms occurs. And what are the consequences of a broken window regulator with regard to the main inspection? Before 2012, a defective window regulator was considered "as a defect". But that is no longer the case these days. The window regulator has namely no influence on the driving behavior or the safety of the vehicle, so you pass the main inspection even with a broken window regulator.

  • Next, the insulation of the door panel is removed (insulation mat / plugs, etc.) so that the mechanical and electrical components are accessible.
  • Next, the vehicle window and the window regulator motor are removed.
  • The mechanic can then replace the window regulator motor or the glass.
  • In the last step, after all components have been reinstalled, the window regulator is taught (programmed).
  • In vehicles with a frameless window (often coupes such as the Audi A5, BMW 4 Series or Mercedes C-Coupe), programming is often only possible with a diagnostic tester.
  • With other vehicles, it is usually sufficient to let the window go all the way down and once all the way up.

How modern window regulators work

When the button that is supposed to move the window up and down is pressed, a cable is wound up or unwound inside the door over pulleys. The window holder is guided up or down via a rail. Anti-trap protection is also integrated into the system. This is important and protects against injuries. The type of anti-trap protection is implemented differently depending on the vehicle.

In this tuningblog category there are guides and instructions for common defects/repairs on the vehicle and for installing accessories/tuning parts. Our articles explain in a simple way common defects and the corresponding repairs, as well as explaining how the first signs of a defect become noticeable. In most cases, we also have initial clues to the repair instructions in our repair instructions approximate The costs of the pending repair are listed. The goal of our subcategory “Auto Repair Guide“ is to create a head start in knowledge for the next visit to the workshop with initial tips. This may save you from tedious troubleshooting and small things can perhaps be done directly on your own. The same applies, of course, to the installation of accessories/tuning parts. Here, too, we would like to help with the implementation with instructions and tips. There are many other posts on this as well.
