Power Window Issue

My 2018 Tacoma rear driver side window is not going up or down correctly. See video.

Could this be an issue with the regulator arm?

How can I fix this?

Have you tried the "re-indexing" procedure? Pretty simple to do, look up the steps. Do that first before trying anything else.

 

My passenger rear window just jerks a bit going up but ok going down. Almost like it is sticking or needs some lubrication not sure but it is not a big issue but could be if not look at.

Where do you find this re-indexing that you talk about

 

My Corvette had a re-indexing procedure. I am just assuming they all do. But maybe not on the truck since it has a full door frame?

 

There is a power window reset procedure, found in post 10 of this thread:

I don't think that's going to help in this case though. From the video it looks like to me that the window is slipping out of the track as it goes down. There may be something wrong with the track or the guides that hold the window in place. The only way to know for sure is to take the door panel off and take a look at it. *Caution* If you do take the door panel off make sure the cables for the door latch and locks are back in place properly.
