As we've seen before, when the window has issues dropping to clear the roof it's often too much slack in the regulator's cable.
I replaced the regulator with a nice used example last month, worked right. Then about a week ago it started to act up and hang up on the edge of the seal.
Basically, I'm wondering if this regulator is also crapping out in terms of cable tension, or if it's possibly another culprit entirely. I plan on removing the door panel this weekend to take a look (also to replace broken clips from last time). Is there a chance it could be in the door handle sensor? I guess I'll find out Friday if it is the sensor, the cable, or just the glass somehow getting repositioned in the rubber clamps.
