Reconditioning Power Windows? (1 Viewer)

[4runnerguy]

I have a new to me but very-well-loved South African 105. Mechanically, it's been pretty solid but the interior needs lots of love. The driver's side window strains a little going up and down, but I suspect the motor is still good. The track of the window has tons of dirt in it; the master switch, which will need replaced, looks like it was buried in the dirt.

Are there best practices for cleaning up/reconditioning power windows and the related mechanism? It looks like the seals and gaskets need replaced. Is there any kind of lubrication I should use given a particularly dusty environment?

Thanks!

There is a 10mm bolt at the bottom of the riser where the glass sits, it holds the glass panel in place so it doesn’t tilt. Make sure that is tightened accordingly otherwise the whole glass panel will eventually jump off the guide rails and you wouldn’t be able to close it. I use the WD40 silicone lubricant spray, works well with rubber, glass and plastic and metal joints of the whole power window assembly.

A couple of my motors really seems to strain going up. Is this a lack of lubrication or should I order motors?

Possibly, I would check for any debris or the rail first to rule that out.

Last week I cleaned my window runs with q-tips and then greased (with q-tips as well) using Honda Shin Etsu grease per the reccomendation of @roadsalt 's thread here. Even when applying grease, there was still a lot of black grime coming out of the runs, so I may need to re-clean again this summer. However, my windows were slow in the winter prior to this and now they fly. A thin layer of this grease works well for reconditioning the rubber and keeping the windows moving freely.

If yours are very bad, you may need to take the runs out and fully clean them prior to greasing. That would also give a chance to repair or replace any bent or broken runs.

On top of all discussed above: Make sure the clock spring in the widow mechanism is intact. The motors get's slow with time, but my 3rd gen 97 4Runner windows are fast for being 27 year old vehicle, so motors are not always to blame. The contact points in the master may not conduct 100% and this could be an issue too. Clean all earth/ground points. Check the fuse contacts that feeds power to the switch, it may have some corrosion as well.
