Default Window regluators

My drivers side window struggles to reach the top. I have replaced the regulator spring which was broken, but the window gets to 2/3 up and then slows down to a crawl. By the time it gets as far as the weather seals at the top, it stops, leaving a 1/2" gap for the rain to get in. If I open the door and hit the button again, I can get it to go all the way up. I have checked and greased all the tracks, checked the bolts all over the door mechanism and I am stumped. Does this sound like a stuffed regulator or something else?

Cheers
Kev

To me, it sounds like there is something putting the window in a bind and that is holding it up. Perhaps when you replaced the spring you inadvertently changed the angle of the window causing this.

does it work fine with the door open? If yes, try removing the door panel and adjusting the mounting hardware.

Is the window alignment correct? Could it be binding on the weatherstrip somehow?

Did you install the spring with the regulator in the full up position? Keep in mind the spring is there to help with the up motion. It has to compress when you lower the window and unwind when you raise it.

Try it see what happens. You could also have a very weak motor or regulator with too much play at the scissor.

Thanks Jim, so if the motor is week, would it need replacing or can they be tweeked?

Door glass is binding on the weatherstripping as the window gets near the top.

I have the exact same problem except mine does not slow down 2/3 of the way.

I don't think you can tweek it. You can take it out and clean it up. Make sure the ground wire is not corroded. Lube the gear and thats about it. I did that first. You can get them rebuilt. I bought a new Delco motor. Its no better then the original 28 year old one. My problem is the regulator. The spring is good, the motor is good but what happens is when the window hits about a 1/2 inch from the top the regulator buckles and the window will not go all the way up with the door closed.

Basically if you take the regulator out to properly position the spring cehck and see if there is any play in the scissor, there should be no wiggle space.

Your problem sounds different because you say it slows down 2/3 on the way up. Thats sounds like the spring wasn't put in right or the motor is weak. If you manage to get it up except for the last 1/2 inch thats a regulator problem.

You can try adjusting the positioning. Its real tempermental.

I dont think that it is binding as it is still very week even with the door open. It seems like two issues:

1. There is not enough power to press in to the rubber to make a seal, as soon as it gets the slightest resistance it stops.

2. There is not enough travel on the window. I have adjusted the upper stops to the maximum they will go, but the window needs to go about 3 or 4 mm higher to make a tight seal.

Driving me insane it is

With the window at 1/2 grab it and pull up and push down. How much wobble or play is there? There should be almost none. If you have a lot. The regulator is worn out.

C3 I just wrote this thread over in the TECH section maybe it can help you too.

81 just a suggestion make sure the motor and regulator are bolted together very tight. They are bolted together with three bolts right were the gear, bearing and teeth meet. They may look tight but with all that spring power they may not be. If they move it throws the motor into a bind which doesn't make it work correctly. If all that is tight and it still will not work more than likely you have a weak motor. Changing motor out isn't that bad. But you have to remove the regulator to do it. Just be careful about all that string power and bolt the regulator in the center hole locking it. Don't want to have to call you 81 nine fingers LOL. Good luck

or C3 nine fingers . Thanks

I just remembered something when you release the window from the channels....the large upper track does come of. Just slide it off the rollers while everything is in the door and then pull it out through the access port.
