    Thumbs down Driver door window trouble

    Hey gents,
    I did a quick forum search but didn't find what I was looking for..
    Recently, my D1's driver (electric) window started playing up mechanically. Basically, it will go down when asked to, but seems to go too far down into the door, the when I ask it to wind up again, the window tilts forwards and jams in its runners/frame. It was possible to get the window up by guiding it with my hand at the same time as holding the switch, but I grew tired of this and pulled the door trim off to have a look inside.

    In the bottom of the door I found some parts with a broken bolt in one of them. So then I needed to know where these bits go and figure out what they do and how they fix my window problem. I continued pulling the door/window apart; first the motor out, so then I needed to support the window itself, and then unbolted the main window scissor pivot (big gold plate) but then the nylon block on the end of scissor arm had fallen out of its track on the door. The bit that broke off bolts to the big gold plate and I gather its a limit/stop for the half gear on the scissor arm, I'm just not sure of its orientation. Also at this main pivot is a big spiral spring that is now loose, again, I'm not sure of its orientation.

    Hope I'm able to fix this with some experience and insight from anyone this may have happened to before, or has dis/assembled doors or windows before.
    There's not much room in there for hands and you can't see either!
    Hope anyone can help!
    Cheers

    Looks different to what I recall when I did mine ('97 model). What year is yours?

    I found the easiest way was to remove the entire regulator (scissor) assembly from the door. On mine there were 2 bolts in the channel that attaches to the bottom of the window. Loosen those and you can slide the channel a bit and remove it from the window as the bolts are in keyhole slots.
    Couple of other bolts and the whole lot will come out with a bit of wriggling. Maybe take a photo as its coming out so you remember for when it comes time to refit it.

    There is a thread around somewhere about replacing the rollers with a sliding door roller from Bunnings, but I couldn't find one to suit. Ended up replacing the whole regulator.
    Couple of years later when I did the passenger side one, I removed the good roller and pin from the old drivers door one that I still had lying around and fitted that.

    Edit: One of the cheap plastic jaw spring clamps from Bunnings etc makes a good window holder if you clamp it just above the window sill.

    Hi Niche

    There are some nylon rollers that break in the mechanism.
    A friend and myself are now making aluminium roller replacements for ourselves, these roller's are easily made and then fitted.
    Start by first removing the mechanism, whilst holding the window pane up by using a length of plastic packing strap around under the bottom of the glass and tied over the top of the door frame.

    With the mechanism free, grind the end of the roller's shaft where it has been swaged over and punch the shaft out of the arm, fit the new roller and reassemble, using a mig welder to fasten it with a run of weld.

    The broken bolt could be a result of the problem rather than the cause. I found my Disco window doing similar things - when I investigated I found that because of a missing stop rubber ( Like a door stop) at the bottom of the door, the nylon guide popped out of its runner, and when it came to going up, the scissor system got all out of whack. I used some actual door stops bolted to the bottom of the frame to solve the problem.

    Please ensure you wear some decent leather gloves when handling the 'Scissor' arms. It didn't get it's name for nothing & a wrong move can have your fingers off as it flops around.

    Smile Fixed!

    Cheers for the replies guys.
    I had another crack at it this evening with a clear head, and with total success! I decided it was pulled apart far enough to justify taking the whole regulator out of the door and sussing out how it works/what goes where. Put it all back in with a new bolt where the stop broke off and it works like new again!
    The only thing of any minor concern is that spiral spring (which turns out helps the motor push the window up) seemed quite loose in its travel, like not doing a great deal. Perhaps it was just worn out. I made sure I had it working the correct direction, and that it could be wound around one more revolution, but then it was way too tight. None the less, a perfectly working window again!
    cheers again!

    Good work!!
    Definitely easier to pull the whole thing out than stuff around with it inside the door.
