Comfort for retrofitting - the electric window lifter!

[Update: 10.10.2023] This post was updatedto take more recent information into account. If you no longer want to roll up or down your car window yourself, there is the option of retrofitting electric window regulators. All you have to do is press a button and the rest happens by itself. Especially when a car is not yet equipped with one, the question arises as to whether you can retrofit an electric window regulator. And in fact, this works with almost all cars. Depending on the model, however, it can involve varying levels of effort.

Retrofit window regulators

In order to be able to retrofit window regulators, there are corresponding sets available on the market. These contain almost everything you need to retrofit electric windows.

This is necessary because you have the so-called Shear often has to be replaced. These are responsible for the window moving up or down. Depending on the processing, this is a little more complex as it may be necessary to drill out the rivets. The rivets ensure that the old scissors are firmly connected to the disc and reliably raise and lower it. At this point you have to work carefully so as not to damage the window. Once that's done, you have to remove the disc and can then remove the old scissors and install the new ones. This step is relatively easy because the scissors are usually attached with hex head screws.

The power supply for the window regulators

So that the window regulators also have power later, you have to lay a corresponding connection cable in the driver's compartment. Especially with regard to the cable length, you have to think beforehand about where the switch for operation should go. It's not that the cable ends up being too short or is constantly under tension. The best option here is to arrange the switch directly on the door, in the center console or in an invisible place. There are special solutions, especially for classic cars. For example, you can convert the original window crank into an operating button. If you push it forward, the window goes down; if you pull it back, the window goes up (or the other way around). Depending on the selection, this involves a different level of effort. Extensive processing of the cladding may also be necessary. To ensure that the cable is laid properly, it is recommended that it be routed through a suitable connecting hose that flows into the A-pillar. The cable is then routed to the switch.

If possible, connect to the ignition plus

And another cable is needed to a power source. To ensure that the power requirement is low, you should ensure that there is no “permanent plus” when connecting. So the switch constantly draws power, for example for lighting from the switch. Unless, of course, you want such lighting. However, it is better to connect it to the ignition plus (or switched plus) so that the vehicle battery is not drained. If it is connected to the ignition plus, the lifter only functions when the ignition is activated. With regard to TÜV, no tests or entries are necessary when retrofitting window regulators.

  1. Hello, is really a very great video and detailed information on how to easily convert your car to electric windows.
    Unfortunately, however, I do not find any information on the site where to buy the set.
