Hello, This is the 3rd time I have asked about the same thing. I have gotten good advice but can't seem to get it to work. Problem, window on drivers side is screwed. I have disassembled and reassembled 3 times. Loosened everything took window to the top adjusted everything, tightened everything. Window rolls down beutifully in the tracks and smooth. Will not roll up at all unless I loosen front and bottom sash tracks. Then window rolls up but hits upper frame about 2 inches from top and atleast an inch from the back. I can push the window into place but difficult to do while driving cdown the road. Only one obvious problem, the little tension roller (attached to the outside piece of trim) has broken off and I haven't found a replacement yet. I thank anyone for any advice. Bruce

The little roller probably fell off about an hour after the car came off the assembly line. Don't worry about it. If you you are still having problems there is a possibility that the regulator is worn out. Keep playing with the tracks, it's a pain I know. If the window rolls down smooth, loosen the short rail on the inside of the door about where the handle on the door panel sits. Have some one help lift the window as you roll it up and see where that rail wants to move to.

The roller is important, and they don't all fall off as soon as they leave the factory. All of my Zs still have the orignal.

More likely you are having problems with the guide tracks.

Is the felt in the tracks new? It is very cheap, and still available from Nissan. If the door panel is off, you will have the problems you describe. The window counts on the panel being their to exert slight pressure against the glass as the window nears the top of it's travel. Seen that one a gazillion times.

Try to push outward slightly on the window as you roll it up, and see it it goes where it is supposed to.

If your regulator works (and it sounds like it does), then your window closing problems are most probably related to alignment of the glass. This can be due to either age of the parts, or adjustment. Grease all the pivot points on the regulator, visually examine the felt in the tracks (common for it to get bunched up at the bottom, with no felt at the top - this will put the window out of alignment as it nears the top). If your roller is toast, replace it.

Window Roller, Left, 70-78 Part # 30-2151 $18.49 / 0 lbs.

Did you go back and read my post to your previous posting of this?

The window roller is required to push the glass inward as it reaches the top of it's travel. The inside door panel and the fuzzy strip attached to it, push the window outwards. Between these two and the window frame and front sash the whole thing is maintained in the center of the window frame.

The fuzzy gasket in the top part of your window frame should be FUZZY, no grease, no bare rubber spots. Grease here will just get all over your shirt sleeve. Bare rubber will just prevent the window from rolling up and down smoothly. The inner fuzzy strip mounted to the panel is what presses against the window to push it out, if it's missing or caked solid with dirt / grease / gunk it will just impede the sliding of the pane. The outer gasket on the chrome trim is to seal the window from rain once the window is closed, it is the roller which locates the window in the center of the frame.

That you have to loosen the front sash and the rear guide channel (there is no rear sash) tells me that you don't have these adjusted right, or that your frame is bent or that it's misaligned.

The adjustment for the window is straight forward. You DO have to have the glass bumper roller installed or it will be a b*tch.

1. Loosen the installation nuts for the front sash and rear guide channel.
2. Roll the window up and down and check the alignment of the rear edge of the glass with the door frame.
3. If the glass angles too far to the rear, move the rear guide channel upward. If it angles too far to the front, move it downward. As a general rule, the rear guide channel bolts will both be at the same location within their respective slotted holes to each other, i.e. front bolt won't be higher or lower than the rear bolt in relation to the bolt hole in the metal door frame.
4. When the glass is parallel with the window frame, adjust the front sash so it is parallel with the front edge of the window. You can just look down from above and ensure that the nylon guide mounted on the bottom channel of the window pane is going to go up and down the front sash smoothly.

If your regulator is not allowing you to crank up the window after this, check to make sure that the spring on the regulator isn't broken. Without this spring it is literally impossible to raise the window. The sheer weight of the pane is too much for the angle / gearing in the regulator. The gear within the mechanism will just work its way out of the teeth on the arm. The spring is what helps you counter the weight of the window pane against gravity.
