Sigh - slow power windows

[KellyJ]

Is there any way to make my windows go up faster? I don't see any reason for them to go as slow as they do. I'm talking about it taking 8-10 seconds to put up the rear door windows, and the rear window, sunroof and front windows take just as long too.

Would taking apart the doors and cleaning the inside of the motors/ window hardware help them go up faster? Or is this part of a larger electrical problem? I mean I could roll them up manually much faster than my windows go now. :bash:

that happened to my buddys f-150 and he needed a new window motor.... but then again thats a ford....

Roll down your windows and clean the rubber window guides. Then spray some silicone lubricant down the rubber guides and cycle the window up and down. Repeat twice.

As a side note, lubricate all weather stripping with the silicone lubricant to stop squeaks and prolong life.

:iagree:
The number one reason for poor window performance, the channels.

Cool thanks for the replies I'll try this out in a few hours. It's finally a nice enough day to do work on my car

Are all of the windows slow? Do they go up/down at about the same speed?

If the driver's window is slower than the others, the most likely reason is a tired/worn power window motor. I see it all the time on vehicles as they start to age and get some miles on them.

The front windows are the quickest, and I noticed when I hit the auto up for the front 2 windows and then pull up the 2 rears, the rears go especially slow until the fronts have reached fully up, and then they speed up a bit before closing completely. I'm starting to think its the alternator

Did you try lubricating the channels with silicone lube yet? I'm positive it's not your alternator because I just got a new alternator and battery (Toyota) and the windows still slow down when I try closing 4 at the same time. My windows were quite slow before taking about 6-7 seconds to close. After lubricating the channels with silicone, they now take about 4 seconds only. The back one is a lot faster than before too.

The windows will always be slower when you close more than one at the same time, especially if the window channels are dirty and not lubricated. The extra friction from the channels increases the current draw needed to operate the windows. Multiply this current draw by 4 or 5 windows and it becomes quite substantial.

Check your fuses

For anyone who revisits this post: take a look at all of your fuses associated with the power windows... actually take a look at all of your fuses in general. Sometimes fuses or the fuse box can build up corrosion or dirt on the connectors. Make sure the fuses are clean! If they're black or corroded on the terminal end: replace or clean them until they're shiny.

I noticed a significant power loss on most vehicles, within different systems due to this.

It would be a good idea to pull apart all the connectors as well, inspect them, and clean them. Throw a multimeter across the switches and check that they are transferring the right amount of volts to the motor. A little bit of wear in all of the components combined could cause a big issue at the end of the line.

Mossberglar,

For a first post your off to a good start!
I just checked mine under the dash and they all had discoloration on the
fuse connectors! Think I will check under the hood next.

My rear glass slows down sometimes.

Does anyone have a wrote up or photos of lubrication? I just like to make sure that I know exactly where it needs to be done, I typically don't like to just go around spraying lube all over haha.

Probably needs a nw motor lubing the channels helped a bit but if it's really slow it's going to be regulator time
