Window regulator problems

[BOYER73S]

I have an ex USA 72 which has been converted to RHD and I have problems with a window regulator

Its the RHS of the car (old USA passenger side) I have worked on it this afternoon and when you wind the window instead of the plastic guides sliding smoothly along the runner and the window going up the arms appear to want want to twist slightlty which stops the guides from sliding and hence the window is very difficult to move in either direction.

I don't think its anything to do with the frame as there isn't really any adjustment there except a bit on the angle on the door lock side.

Maybe the sliders are stuffed or something else is causing them to not slide properly.

Anyone got any clues please??

Maybe the window is getting cocked and binding in the channel. Have you tried the pivot adjustment at the bottom of the window bottom channel. There is a 13mm wrench size nut that you access from the backside that when loosened will let you change the angle of the window as it goes up and down.

are you sure the nylon sliders are the proper ones and are installed properly? Try loosening the window frame and see if something is kinked.

Not familar with that adjustment but your prognosis makes sense and I will check it all out. Previous owner tells me window came out of its channel perhaps they have put it back in slightly crooked also.

Sliders appear to be identical to opposite side and work fine when the door fame is not in and the window not attached to the reglulator.

Ok so I looked and the only nut I can find at the back is the one that holds one of the arms of the regulator in place and allows it to pivot and I don't see how that can affect the angle of the glass

Otherwise you have me stumped, however looking at how the window winds up I think your correct about binding in the channel/ being crooked as one side is nearly out of the channel at the top
now I just have to figure out how and how to fix the problem

More help please.

Hi Clyde, this a picture of the BACK of the regulator and lever mechanism, the part you don't see because it is against the door panel. You can see the 13mm nut I mentioned earlier and notice that there is a slotted adjustment that changes the angle of the window in the window frame. Try changing the angle of the window to see if that helps cure your binding. This assumes of course, that the window fuzzy channel is not worn out.

Aha I felt the nut but didnt realise there was a slot there for adjustment..thank you I'll go play now and see how it goes, it certainly works fine until I put the frame in place so I don't think it is the regulator itself
as everthing slides nicely, even with the window attached, its just when I add the frame into the equation that it binds.

Thanks.

Ok that didn't solve the problem either.

Here is what i did

I checked the opposite side window to see what happended with the bottom frame of the regulator (the one that the window attaches to) and it stays totally level all the way from top to bottom
as I would have expected

I adjusted the door I am working on to have that bar level at the bottom by adjusting the screw you talked about then tested the winding up and down without a window attached.

As you can see in the pics the LHS of the bar tilts quite a bit down to the left by the time it gets close to the top.

One can now only assume from what I see that its the regulator thats the problem as the frame is not involved at all here.

Thoughts????

Let me take a look at a regulator tomorrow and see if I can identify what could cause your problem,,,,don't go away!!
