No, the one touch front power windows were not a feature on the W201 models. There are two way to get this feature. First, there is an aftermarket module, available from Bergwerks at

The other method is a modification of the window rocker switch. By disassembling and removing the spring loading on the switch, it makes the switch a "three position" mechanism, down, neutral/off and up.
