This is getting massively aggravating. I removed the top two regulator nuts, but can't get the regulator to collapse more than maybe a half-inch. So I removed all the regulator nuts, and am tugging with everything I have on this cursed window, and I can only get it to rock maybe an inch or so. It's still completely stuck in the front, but I can't for the life of me see what it could be stuck on. I've followed the regulator around with a flash light as best I can, and as far as I can tell, the cable is fully intact, and doesn't seem to be wrapped around anything it shouldn't be. In fact, I can't see any evidence of any problem with the regulator, so I'm very reluctant to cut it - I still think it might just be that the clips holding the regulator to the window have broken, and a piece of one of them is wedged between the window and the door frame, or something like that. Any other ideas on how to get this wretched window loose without breaking it? Thanks.
