I have a 99 4 runner that was involved in a collision. It was fixed and looks great, but the auto UP window button takes the window up and then back down half way. I think it is an adjustment problem with a sensor telling the motor where the window is, but I have not had the door panel off and want to know how it works before I tear into it. The body shop had to reskin the door, so that would be the cause of the window to go haywire, everything else works as it should. Can anyone help me?

Wierd, mine did that today for the first time? Didnt happen again though

 

Mine does that as well after replacing passanger side window. Maybe I ought to talk to one of the guys at Toyota. I keep thinking I probably need to have them reset the window relay timer or something..

 

try this,roll the window down but hold the button down also until it gets all the way down,then roll it back up the same way-hold the button in the up position until the window is all the way up,it may need to be reinitialized

 

Tried that, didn't work, still does the same thing. Thanks for the idea though, anything else?

window motor

 

any luck on this issue? the dealer wnated me to set up an appointment when I called them. I know they are just trying to charge me 100+ just for diagnose so I didnt go.

 

Does the window go down about half way then stop? If so, it could be the Auto-Up Safety sensor. While in Auto-Up, if the sensor detects sufficient resistance while closing, it will automatically reverse and open the window about 1/2 to 2/3 to prevent injury and/or damage. (Safety feature.)

 

just a thought maybe its off track since that happened to me after some tough wheeling.

 

does the window goes up w/o using the auto? if it does, id suspect the switch itself.

 

I think it does sound a bit like the auto up safety sensor, but Im no expert, because my 04 taco doesnt have auto up, only auto down...

 

my auto up feature does go back down about a half way. I think I should check the window track. the only thing that doesnt work is the auto up feature. I can roll it up all the way using the traditional up feature. I think the thief pryed through the window track/frame to break into my truck. track may have been damaged/bent. Thanks for the idea an i'll go ahead and check tonight.

 

sounds like its binding in the tracks. does it go up to the same poisition each time?
id take it back to the repair shop and have them fix it.
