Mercedes Actros MP3 Window Regulator Mechanism Only Comfort Function Left 08-12

* To choose the right window regulator for your vehicle, check first to see if the vehicle is equipped with the Comfort Function.
If the window mechanism can be automatically activated with only one-touch on the switch, then the vehicle is equipped with the Comfort Function (usually the switch has a specific symbol).
If the window has Comfort Function and stops elevating when slight pressure is applied to the window then it is likely to have the Anti-Pinch system.

If it is necessary to maintain the finger on the switch button for up and down movement of the window, then the vehicle is likely to be a standard version and not equipped with Comfort Function.
If this check is not possible then the amount of wires or pins on the electrical connector can provide some information. As a general rule, standard window regulators have two wires and a two pin.
