I've read the threads and the Haynes manual, but I don't quite follow the correct sequence to separate the regulator from the window. This is for the front passenger window, on a 1987 300e. I have lowered the window and removed the nut at the far left, which secures the slide to the window. I think the next step is to tilt the window and remove the slides, but the window doesn't budge. In order to remove the slides, should I first remove the two nuts securing the slides to the door (not the three nuts attaching the regulator/motor assembly to the door), or raise the window? I'm sure this is easy, but I've never done this before, so I'm stumped, and I don't want to loosen something and FUBAR the entire process. Thanks.
