47-55.1 Window regulator - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jemezcrusher · 07-23-2020, 07:49 AM

Doing final touches on my 1950 3100 and am having issues with a window regulator. Over the last couple of years and have done some wheeling and dealing on parts. I picked up a new pair of regulators from a guy (don’t know the manufacturer) but both failed in the install process. They broke internally as soon as I put any real pressure on them rolling up.

I put my old regulators back in and the passenger seems fine, but the drivers side has an issues. It seems to droop forward and the leading edge leaves a gap at the top curve, and the window is not horizontal in the opening, but tilted a bit.

I am not sure if this is an adjustment issue or a worn out regulator. I see you can rotate the pivot a tad but this seems to have little effect.

Looking for suggestions on a good regulator supplier or advice on how to get this worked out

You do have the correct regulator for the one piece windows?

Then do you have the roller (s) in the track in the door? I remember fighting that on mine when I replaced the glass in the 70's Trying to get big hands and arms in there to get it all in place was a pain.

Yep. Right regulators, just kinda droopy. I think it is tired

I once had a Model A with a door window that would drop in the front leaving a 1/4" gap no matter what I did. Finally I gave in and had the glass shop cut me a new window glass that was 1/4" taller at the front (IOW not square). It looked and worked perfect.

Sounds like a good solution for your problem but I have a frame the goes around the window

In that case you would simply add to the BOTTOM of the glass. The window frame would still fit as normal, and the extra glass would be hidden down inside the door (you could never tell the window wasn't square anyway).

My comment however was offered just to illustrate my experience with this same situation and what I had to resort to when no other solutions worked. In your case the obvious solution is simply to try a different regulator.

The only thing I can think of is something worn enough so it leaves some slack.

The rollers are all in the channels where they belong in the back side of the inside door panel? That was my fight back in 1973. I had a heck of a time getting those rollers in the channels.

That was the hardest part when I tried to figure it out on the passenger side went in. I have the scratches and bruises to prove it. I got one arm stuck in the door for about five minutes. Learned the install techniques on the passenger side, and it works great. Window is square and operates as it should Driver side droops so will have to replace the regulator I guess. Will look for an original that is in better shape
