Power windows super slow

My 85's power windows roll down agonizingly slow. I wonder if the rubber is swelled, or if something is out of alignment...?

It's not the usual bad bushings, the motor is straning like the window is hard to move. I usually help it with my hand. When it's raining and the glass is wet, it moves ok. I might just lube the track (but that probably won't last).

Anybody done any window work? Got any ideas?

Yeah Mine got that way, The passenger side on my new one is like that too. It APPEARS to be that the rubber is squeezing it... but i proved that wrong. The middle stabalizer bar that turns in the door when the window goes up and down loses how easily the wheels go along it, so it moves slower than the other side of the window, if you arent careful, you'll pull out one side of the two clips that hold the window. to prevent this, go down a few inches, then bump it up, then down a few inches until it gets slow again, then bump it up. etc. When you have the time grease that bar and see if it'll help, it did me.

go to walmart or your part store and get a can of silicon lube in a spray can and lube up your window channels.  good as new :D  this is what I did to make mine work faster.

You might check the guide bushing, a plastic square piece that keeps the window channel properly located.  It's probably buried under grease and not easy to see.

Same issues with mine only that it binds so bad at times the windows stop working because they think it's either all the way up or all the way down.

Don't be afraid to pull the motors off and get some grease on those gears. Also greese up the veritical tube in the door that the regulator slides up and down on. Get grease on the horizontal track below the bottom of the glass.

Don't use really thin lubricating sprays. You need something that sticks and remains on there and does not dry out. The best choice is always thick old fashioned grease. Better yet is the marine grade grease that better withstands the elements. The only spray I recommend trying is white lithium grease which leaves a white thick coating. Silicone lube and WD-40 type sprays does not last very long and has to constantly be reapplied. Who wants to take off a door panel repeatedly?

The biggest problem I have now is the dried out and cracked vertical window channel seals. Mine will have to be replaced as they cause an incredible amount of binding as the glass slides up and down inside them. It gets it's worst when the weather is cold.
