Making window regulators work

[rhondo]

Hello everyone,
I have a 1970 international Scout and am having a problem with the windows rolling up. They roll down just fine, but when you roll them up they bind and have to be pulled up the first 2" - 3" of travel. The front guides are new, the back ones look OK. The adjustment screw in the front guide seems to have no effect. New regulators are pretty much unavailable. Manual , not electric.
Any ideas?

Thanks!

Have you taken the regulatorsout, & know that the turn freely? If they do the glass is binding somewhere. You could try spraying some greaseless lubricant on the window channel to see where it's binding, but this would be a temporary fix. Larry.

I did remove and lubricate the regulator, but did not check the operation. should you be able to clamp the window regulator in a vice and simulate it's operation by rolling it up and down in the vice?

You can simply leave them in the door and unbolt the glass from them to test their operation. PLUS, slide the glass up and down in the channels at that time with them unbolted to see if they are free. ONE of them is binding, until you figure out which, you are wasting your time.

Are there adjustment nuts in the regulator frames? If so, see if you can find the "footprints" of where the bolts once sat. Also , please dont get angry, but one mistake when you take them out is that some circlip, fastener or washer didnt go back the way it was supposed to. Study the function of a working regulator if possible. I've done this maybe a 100 times and i still always make a mistake once in awhile and thew window will bind.
