josh817 Posted October 21, 2012 Report Share Posted October 21, 2012 Well... I always loved the 521 window setup because unlike the Z, it's straight up and down, and you don't have to worry about lining up guides so it doesn't bind up or anything. Hah, my window is binding up now. I think its something in the crank system. I roll her down and every time the handle is in the 9 o'clock position, on the way down, it makes a thud. On the way up, in the same position (the handle rotates through 9 o'clock twice), the window gets jammed. It won't go up until you lift on the glass. I can move the glass/arms in the door just fine by hand, and I checked the guides for clogs, nothing wrong in there. I check if maybe my door opener rod was catching on the window, nope. It sounds like its the cranking mechanism, particularly the gear that the handle is attached to since it happens at the same point according to the handle. This problem just randomly started happening. The other side works flawlessly and smooth. Mine use too! Any thoughts? Here is a 1 minute video of the situation: http://www.youtube.com/watch?v=GM8-raSaZVc&feature=youtu.be Thanks for your time. Quote Link to comment
metalmonkey47 Posted October 21, 2012 Report Share Posted October 21, 2012 My 620 passenger window does the EXACT same thing, but it was so inconsistent that i never bothered to look. Tonight finally got stuck and barley got it up. Curious what you come up with, since your and mine are both identical problems. Quote Link to comment
Miler Posted October 21, 2012 Report Share Posted October 21, 2012 I too have this same exact problem, it just started doing it one day Quote Link to comment
wayno Posted October 21, 2012 Report Share Posted October 21, 2012 It is likely the window crank assembly is missing a tooth/teeth, you will need a new assembly. Quote Link to comment
dat521gatherer Posted October 22, 2012 Report Share Posted October 22, 2012 I think wayno is correct. Quote Link to comment
oldskoolvws Posted October 22, 2012 Report Share Posted October 22, 2012 Some say the glass is half full, some say half empty. I say opportunity = most awesome electric windows. Quote Link to comment
DanielC Posted October 22, 2012 Report Share Posted October 22, 2012 Before condemning the window crank assembly, try spraying a silicone lube in the window tracks. Does the window wobble around? if it does, sometimes the window will twist slightly in the tracks, and jam. By adjusting the front window track to the rear, you remove some sloppy fit, and the window actually slides up and down better. Quote Link to comment
Guest Rick-rat Posted October 22, 2012 Report Share Posted October 22, 2012 Mine did this on my 620 for a few months before the regulator failed completely Quote Link to comment
Madmax Posted October 22, 2012 Report Share Posted October 22, 2012 Some awesome member did a power windows in the "how to section" although its not a budget thing, stupid kit costs $250 if i remember correctly??? hope yaw get-er fixed... Quote Link to comment
jon521 Posted October 22, 2012 Report Share Posted October 22, 2012 had the same problem with mine during the summer if i let the window down too fast, it would bind up. but everytime i would just lower it back down and go back up slow and it would work. i am also interested in what you come up with Quote Link to comment
konig209 Posted October 22, 2012 Report Share Posted October 22, 2012 My windows rattle when theyre down. Quote Link to comment
wayno Posted October 22, 2012 Report Share Posted October 22, 2012 My windows rattle when theyre down. 510(70ish) window channel felt will fix it. So will datsun roadster(66-70) felt, but it's expensive. Quote Link to comment

socaldatsun Posted October 23, 2012 Report Share Posted October 23, 2012 Just curious what window regulator can be swapped with the 521? Quote Link to comment

socaldatsun Posted October 24, 2012 Report Share Posted October 24, 2012 Dang my driver window is all jammed up aswell, actually broke the handle one day lol Quote Link to comment
josh817 Posted October 27, 2012 Author Report Share Posted October 27, 2012 I'm gentle with mine. I put generic felt on three sides and a rubber strip across the top so I can keep the rain and wind out. When rolled down though, my window rattles too. It rattles at the bottom, inside the door. Both windows in my truck can flop around pretty bad when rolled down. I'd say its between the window and that cross beam in the door. All that rubber that held the outer door shell to the beam on the inside, and consequently all the window felt and rubber, is long gone somewhere in the bottom of the door. Unrelated to the window issue, I was told I could fill the gap between the beam and the outer shell with that foam spray "Great Stuff" I think it is, that you would spray around outside faucets on your house. Daniel, I will try lubing the guides but I was under the impression that they were not adjustable. I don't see any slotted areas for the bolts to move, its all set permanently which was why I was all "woooohoooo I don't have to wrestle with this shit" since the window goes straight up and down. Likewise ever since I took about my Z door, I was never able to get it to roll nicely without the front lagging or whatever. Not surprisngly, the position of the window crank, where it binds, is the same position when the window is all the way up. I'm suspicious if I may have forced it up too hard and broken a tooth off. According to the manual all I need to do is get the one lever arm off the glass, the glass drops down into the door, and I can then pull the regulator out. Or maybe I have to pull the glass out, and then the regulator. I think I saw in one of the pictures that the front guide, closest to the regulator, is also the metal support that goes between your window and the winglet? I'm apprehensive about this.
