�67 Driver�s Window VERY hard to Crank Down; Cranks up Smoothly?

You may have a rusty coil spring in the window mechanism. If you decide to take it apart, I highly recommend installing a new spring..... not very expensive and the window will work like new. Does it make noise as you attempt to raise it like the spring is "catching"?

Thanks, Stephen,

I haven't heard anything unusual so far, but I will listen carefully next time I roll it up.

My old Long Island Corvette catalog shows this part below as a coil spring - is that what you are talking about?
09-45C Window Mechanism Coil Spring (Std & PW) ___________ 63-7 (2 per car) 25.00 Each

if that is the culprit, does it make sense that it rolls up fairly easily; but rolling it down is very difficult?

Mark, had same problem with my windows in 64 Coupe. It was a rusty spring, however, took off the panels and found the spring location, then flooded it with white lithium grease with extension tube on can of sprayer, worked perfect after several revolutions. Trying to get those regulators in and out is not fun, good luck, worth a shot before you spend a bunch of time and money on it. Dan

Dan - will do...lube the hell out of it!

Mark - Any work done on the window mechanisms recently? NO. If not, a couple things to mention once you get in there. Look at the channels, front and rear to see if any of the adjustment screws are loose and maybe they aren't in decent alignment now.<< Will do Also, maybe check the wiring connections/grounds to make sure they are good to go. < mine does not have power windows When you drop a window, it's less strain on the window motor than coming back up but that's why they used the coiled spring. When you lower the window, it's actually loading the spring and the spring, OK, so if it's rusted, it could be really loaded now, eh? hope it doesn't let loose all at once as it unwinds, assists raising the window. Let us know what you find.

Mike - if I remember, I'll take pictures...

thanks to both of you (and Stephen) for the advice.

(Agree, that lock knob was the hardest thing to get off!),

I have the door panel off and was hoping to see "a rusted coil spring".

Photo below is what I see w/o disassembling further...
is the coil spring inside the dome-like cap surrounding the window crank shaft?
if so, do I have to use some kind of a puller to get that off?
or is it buried behind what I'm seeing in this photo?

Also, my door pull has always been finicky (hard to open).
looks to me like I have a broken return spring on that mechanism see next 2 shots (looks like it should hook at the end of the screwdriver tip in the 2nd shot, right?
I looked at my old Long Island's catalog and don't see that spring...do you guys know where I can get one?DSCN7116.jpg DSCN7117.jpg

whadya think? - and again, thanks for the help and advice...

This is the coil spring with respect to the crank on the regulator.
With the access panel off and a mirror you should be able to see it.

PS Just be careful in there with your hands if something lets go.

sent me your snail mail info and i ll send you a spring, on the cuff. the spring that rusts will be found once you remove the window regulator in the event you can't lube it thru the access panel.mike

Thanks so much, Mike
my snail mail address has been sent to your MDmissle email address!

Rich, thanks much for that image - now I know exactly what and where to look for it.
Also, thanks for the safety warning! after reading the initial responses - if that sucker is rusted and overloaded - man it could pop with a lot of force - I WILL be careful!

Mark - Here's a pic of the aftermarket PW regulator I used for my 61 Corvette, showing that helper spring. To get to the spring to replace it, you'll have to remove the regulator from the door. Mark all the bolt heads on the inside skin of the door, you'll still have to do some adjustments when you put it back but that will help get you somewhat situated.

Mike, thanks for your guidance - I'm hoping I can just lube the heck out of it and get it working smoothly again - but, if not, I understand what you're saying...appreciate the insights of those who have gone down this road before
