How fast are your windows?
 

I have a 74 911 which had power windows that were so slow it was painful to watch. I put in new window chanel felts and associated seals and the new 3 arm style regulator and the window motor as installed in the C2 and later cars. Everything is well lubed and nothing appears to be binding. The window speed is faster on the way down than up. They are a huge improvement but they are still not as fast as the windows in my Toyota Tacoma or my wife's Honda Accord. How do your power windows compare to the other cars you own? Any suggestions?

Just did the same thing. In my 77 Carrera. Faster than it was. But it seems about 1/2 as fast as my 2 Ford trucks. If that helps.

But I try to keep in mind that this design is almost 25 years old. We like to think our cars are timeless. But technology has improved a few things. Motor controls are one of them.

Mmmmm.....faster than Mrs. Zielke's Toyota 4x4, but slower than my F150 pick-em-up truck. (Real helpful, eh?)

Over the years, I've replaced both window motors w/ used parts - one is fast, the other slow! Tired vs. peppy? Older model vs newer? Mystery to me.

Lubricating the 25 year old arms and pivots inside the door panels would be a start.....you'd be surprised on all the gunk and crud in there.

Dont know if this will work on a P car, but it is a common problem on similar aged BMW's the window switch is the problem, all you do is clean all the gunk out of the switch with elec cleaner and alls well again.

mine worked pretty well, until I put new OE window felt seals in.
Now they are very slow!
Hoping they will pick up speed as the seals loosen.

I bet alot of us wished our biggest problem was that our windows closed slowly compared to those in our Toyota. http://www.pelicanparts.com/ultimate/smile.gif Just Kidding...

Try cleaning out the switch as well as lubricating the joints on the regulator arms and the teeth/gear as well. This should get it as good as it will be, but you may never catch up with your ricers. Just be happy that it actually fully opens and closes.

Good Luck.

Leave the door open and operate the windows. If you see a marked improvement in speed, its due to the relief from the slight window frame flex that occurs when the door is closed tight against the seal.When the felt channels are new or damp, they increase the friction against the glass.
If it operates slow in all conditions, it may be the motor or the other ideas noted. Just a thought.

I have no complaints on my left window, but my right one is bloody slow.

try swapping the switches over

The bottom rail has one adjustable allen nut and one fixed. You can adjust the front to rear angle the window goes up at. I took the door panel off sat in the car, closed the door and adjusted as the window went up/down. Seemed to help some. Then sprayed silicone inside channel and that helped alot.
