92 E300 W124 Drivers window rolls down when unlocking or locking car
 

Drivers window rolls down when unlocking or locking car from door or trunk.
also cannot roll down drivers window down without the express engaging.
after the window is all the way down you have to turn the key to the off position, then back on to roll back up.

I would apreciate and help with this. Could it be the window switch. Can I use one of the rear ones because one of them have disabled because a clip keeps slipping off.

I have not had to debug a problem like this. But I can tell you this car uses something called the "convenience relay" - might not have the name exactly right. The front window switches and door locks are connected to it. It is what makes the express down feature work.

Your car has a feature where the windows can be rolled down and sunroof opened by holding the key in the unlock position. I can't tell from your description whether you have one problem or two. Perhaps the convenience relay is bad, perhaps the electrical switch which is part of the door lock is bad, perhaps the window switch is bad.

You cannot swap the rear window switch in, it is different from the front window switch. On your car only the front windows have express down. I have seen the switches stick in the express position, but I assume you would notice that. Try swapping the two front window switches to see if that makes a difference.

does your car have the feature where you can hold the key in unlock position to roll all the windows down and the other way to roll them up ?
try locking and unlocking from the trunk and see what happens and post the results.

It also happens when i roll down windows from the inside, They go all the
way down and you cant stop it. got to turn the key all the way off then back on to roll back up.

same when unlocking from trunk. as long as you hold the key in the unlocked position the dr window will go down. when locking car hold the key to the lock position the sunroof and all windows except dr. window goes up. the drivers window still goes down.
