1971 window regulator freeing up?

[weaselberry]

Hey all,

Since buying my car this summer (1971 911T) , the windows have not rolled down very easily. Especially the drivers side. They would roll down with a little patience and a little muscle. I read up on the window regulator and realized that eventually I would have to get that fixed or replaced.
Well, I washed my car yesterday and made her look really pretty and then drove it to dinner. Wouldn't you know it, the windows both worked liked they were brand new. I was thrilled. It was like a new toy, and Christmas is a few weeks away.
This morning, windows were back to being difficult. Go figure. How is it that water would temporarily free up the regulator?!?! Any ideas?

Thanks fellas,

The windows on my '70 are also hard to operate, especially the driver's side. On your car, the water seems to have acted as a temporary lubricant, so if you get some real lubricant on the runners, it should solve it.

I think white lithium grease should do the trick. That's what I've been planning on using, I just haven't gotten to the job yet. Any better ideas out there?

I just replaced my window regulator and was advised by the shop that got me the unit to not use white lithium, but to use something more sticky. I used bearing grease, which seems to have worked fine, but it has only been a month or so.

My drivers window has been a problem for years. It cocks slightly in the channel when rolling down. It works fine going up. I have replaced all the channel felt and rubber and tried a bunch of lubricants - none seem to last more than a couple of days. I even had the regulator rebuilt at Stoddards - but they didn't replace the center pivot bolt. I noticed that the pivot bolt was worn, and I replaced it with a good one. If I get the regulator adjusted just right, it will work great - which is where the window is at now. I don't think I have completely solved the problem though - I think a regulator that is not worn will be the final answer.

i have had the same issue on my 73. i just installed another regulator as the spring was broke on the one in the car. i used bearing grease on the sliders on the window. i installed new felts in the frame so mine is very tight. after running it up and down a few times i lubricated the felt with some silicone spray i had in the cabinet and it seemed to get better. mine will get stuck about 3/4" from going all the way down. i have tried adjusting everything possible over and over as it doesnt seem to get any better. if you take your hand and press the glass down a little its flush with the wiper. it raises just fine so i didnt see any stops that needed adjustment to make it go further down. i purchased a used regulator from a 72 so i am sure its a little tired also.
