Hello All,
I just installed a new window regulator/motor assembly in my S420. Now the window express function is not working. Have to hold down the window switch at all times. My question is this, being new to this car, is there some type of reprogramimg for this window function? Thank you all for your time.

Press the window up and hold for about 5 seconds once it stops, then down and hold another 5 after it stops,, that should do it...

 

you can hear a voice after hold for about 5

 

I heard a voice before I held it down, my wife telling it doesn't work. Any other brilliant suggestions.
