FJ40 Window Sliding Down While Driving (2 Viewers)

[Fzjrvakma]

Hey guys, any suggestions on getting my window from rolling back down while I drive? Maybe some grease on the regulator? It will literally roll all the way down if I let it, especially with bumpy rides.

Good chance the mechanism has a ton of wear, bouncing of the window is like turning the crank. If you take it apart you could likely fix it, there might whole units for $$$. Make a plastic wedge like 1" wide, 2" tall and say 3/8 thick - jam it in the window between the track where it goes into the door. Remove it adjust the window, put it back

Is your felt hard as a rock and window loose in the track?

New felt

 

[Fzjrvakma]

All brand new OEM felt and belts. Actually didn't start doing this until I swapped those out.

 

[Fzjrvakma]

That window also got a new (aftermarket) regulator. Maybe it's defective?

 

[JohnnyC]

So your aftermarket regulator was on before you changed the felt? And it didn’t do it … correct?

All info at first would have been better imho

 

[charliemeyer007]

Just because parts are new doesn't mean they are good - especially now days. All the new cars are recalled for something.

 

[Fzjrvakma]

The regulator, felts, and belts were all installed together. I'm thinking it has something to do with the regulator...

 

[charliemeyer007]

If the window is tight in the new felt, then the regulator most likely is it. Maybe they left out a wave washer or 2 that would have provided the proper friction, or some rivet wasn't set properly and movement results.

The torsion spring is meant to balance the glass weight so it’s minimal effort cranking it up. Perhaps you have it upside down or wrong side installed? You should notice different level of cranking effort if so. Or it’s likely just plain worn out, Especially driver side.

Let me know when you are working on this. If I can Ill pop over and maybe between the two of us we can get it squared up
