02 4Runner power window problem

[The-Dude]

Hi guys, the window on the front passenger side of my 4Runner was broken a couple days ago. After I had it replaced, I noticed the power window switch is not working properly. When I use auto up/down to roll up the window, as soon as it rolls all the way up, it rolls back half way down, just like the protective roll down.

I am wondering what could be causing this, and how to fix it. Thanks!!

I am having the same problem on my '99- when I pull up on the automatic switch, it rolls all the way up and then halfway down again. Dealer tells me it is supposed to be this way. I am not quite that stupid about cars, right??? Just bought it to replace my '97 4Runner, which didn't have this issue- anybody know how I can reset or adjust the power window switch so that the child safety switch doesn't engage every time I use the AUTO up button???

Just sounds like a bad installation to me. I bet it's not a toyota glass,the factory glass has the tabs or track already on it. aftermarket glass has no tabs or track on them, they have to clean out your old one & reuse them. sometimes they just glue the a little off where they belong & what you describe is what happens. call the glass guy back!
good luck

Thanks for the info. Well, I searched Google high and low for something about the regulator and found an article that completely explained what I need...thought I'd share in case anyone else is interested. This is regarding the "pinch protection" feature.

"This feature prevents car windows from automatically running all the way up when something may be in the opening, similar to an automatic garage door that will stop if someone walks through the door opening. Although this feature has been used in few vehicles, it is becoming more popular with the manufacturers because electronically controlled auto windows are becoming more standard on today's vehicles. The main purpose of the pinch protection feature is to prevent small children from getting pinned in the opening when a window is accidentally powered up.

Although this feature has no affect on the way the glass is attached to the regulator system, it can make the installation difficult if you do not understand how to reset the feature. Following are a couple of examples used to reset the pinch protection feature on some Toyota, Lexus and Nissan models currently equipped with this feature.

1996-2002 Toyota 4-Runner and Toyota Avalon
These vehicles are equipped with a pinch protection feature called the "limit switch" on both front door glasses. If the glass does not operate properly after a replacement, it may be necessary to reset the limit switch. This will need to be done anytime the power window motor is removed from the regulator or if the window is operated without the glass installed. If you experience this problem, first check the operation of the glass itself by disconnecting it from the regulator and verify that it moves up and down freely. If it does not move freely, check the glass run channel. If the glass does move up and down freely, perform the following to reset the limit switch:
a) Remove the power window motor from the regulator.
b) Connect the power window motor to the vehicle side wire harness.
c) Rotate the power window motor in the upward direction more than six turns or for more than four seconds.
d) Install the power window motor to the regulator and attach glass to the regulator."
