Both links you posted do work, sorry about that. (I got confused when the links on the pages themselves didn't work, but it doesn't matter since you provided both pages - thank you, sir!)
And no big surprise but the problem came back this morning.
Nothing important below, just thinking out loud...
I know I need to take it apart and figure it out myself but until then here's what I'm pondering:
Looking at a motorcraft regulator on amazon
here and I have to wonder why the hell is is half as much as
this aftermarket one?
Why are the regulators for the
front and rear are so different. Aren't they doing the same thing? Is it because the front window is larger with a longer base?
What could cause the window to go up fine 100% of the time but only get pulled down correctly 5%? I'm thinking it's because the glass rests on the clip when it's all the way down but it isn't connected to the clip so it can't get
pulled down - sorta like I can push up a shade with my open hand but can't pull it down if I can't grab onto it. That makes sense. But why would it
sometimes get pulled down? Maybe since it was 100+ degrees yesterday the heat caused the clip to slightly swell enough to grab the glass. I dunno.
My wife's been working nights at a hospital and I'm driving her so she doesn't have to take an uber. Once she's done I'll crack it open. Until then I don't wanna risk f-ing it up and having to drive on the freeway with an open window. At least by then I should have the parts. Gonna order the motorcraft regulator in case I need it. Until then I'm just philosophizing like a damn fool.
