Power Window Motor Removal...

I am looking to buy a set of good, used Power Window motor’s to replace my slow (and broken passenger) motors.

A potential seller was told that the windows need to be down to remove all the parts but has no engine/battery to do such.

To remove the motor (Not necessarily the arms and all other parts), does the window need to be down? Who here has done this? Easy to remove/replace (once I get them, easy to do?)

Thanks

its easy…once its apart you see how it comes out… patience and the window does need to be moved to get stuff out and manuevered…

Does it have to be lowered? to take it out? or all the way up or in between?
