Replaced my window regulator, window worked great for 3 days until I used the key in the door to roll them down, it went down but didn't go all the way back up, stops about 1\2 inch or so from the top now and only goes down about 3 inches and stops. Took apart again and it all looks good but don't work right. Where's the sensor for auto up to stop it and how do you disable it? Or anybody have any other idea what it would be? Thanks
 
Door Window Motor Initialization

CAUTION
CAUTION: Make sure no obstructions are present in the window system when carrying out this procedure.
NOTE
NOTE: A battery disconnect does not require this procedure to be carried out.
NOTE
NOTE: Excessive bounce-back (bounce-back that occurs with no obstructions present) may indicate a non-initialized window motor.
NOTE
NOTE: The front window motors must be initialized whenever: the motor is removed from the window regulator, a new motor is installed, a new window regulator is installed, a new window glass is installed, a glass top run removal and installation and when carrying out any operation in which grease or lubricants are applied to the window system. A new front window motor is in a proportional up/down mode until initialized.
NOTE
NOTE: All front window components (window glass, window regulator, window motor and glass top run) must be installed and tightened to specification before carrying out this procedure.
NOTE
NOTE: If this procedure is only partially completed, the front window motor remains non-initialized and only the proportional up/down functions will operate. A non-initialized window motor may allow one-touch down operation, but does NOT allowone-touch up operation.



  1. Press and hold the window control switch in the UP position at the second detent until the window glass stalls into the glass top run. Once the top run is reached, hold the window control switch in the UP position at the second detent for anadditional 2 seconds.
  1. Test for correct window operation by performing the one-touch down and the one-touch up features.
 
Interesting, I replaced both sides and didn't initialize either. The drivers side works great except it's opposite of what that says, it will auto go up but won't Auto go down. If I hold the button it goes all the way up and down without a problem. the passenger side won't go all the way up at all, it stops about a quarter inch to half inch or so from the top, it doesn't go up and go back down like it sensed an obstruction, it just stops and doesn't go all the way up at all. I wonder if the auto down with key feature made it go too far and broke something cause it wasn't initialized. It went all the way up prior to using the key in the door feature to roll them all down. I'll try this on both sides and see what happens, thanks.
 
That didn't change anything on either side. Must be switch on drivers side. Passenger side only travels 3 inches or so, so something's got to be screwed up internally, guess I'll order another one and never use the key in the door feature again, ha, thanks.
 
Did you take it apart and disconnect it? I don't know exactly what you have to do to get into the initialize mode.

No I didn't, I'll do some more googling before I buy another one, I've never heard of initializing a window before, must be more too it. It worked perfectly fine before I used to Auto down with the key though, that makes me think it's broken again. It doesn't really behave as described in your notes above,
 
Not only do you have to initialize them, but you have to correctly index the smart motor to the regulator. I have a post on here somewhere about how to do that. It's been so long that I have forgotten the details.

I saw something on a different website about pulling a fuse while the window is moving to de-initialize it first, I'll do some more reading around today before I spend any more money. Thanks

Dead battery, then CEL?

I found this one about using the scan tool, is that the one you mean? I'm going to try that later, thanks.
 
No, not that one. It's more involved when you've just changed the regulator. The window position is now out of sync with the motor position. I think that I have in the past, closed the window completely, then disconnected the regulator from the motor. Pressed auto up and let the motor run till it stops, and then reconnected the motor to the regulator (window still fully up). After this, you can do the initialize procedure.

Oh ok, Ill try that. Thanks.
 
Weird. I've replaced both front regulators at different times on my Gen II and never paid attention to position or initializing. Just swapped the motor over to the new regulator. All work normally.

I've often said, "better to be lucky than to be good."

Yeah mine both worked fine with the switch too, I think the auto down with key overextended it though maybe because it wasn't initialized and screwed up the wire on my passenger side cause it only moves about 3 inches, I'll have to look closer but it's a pain in the ass to take apart.I have zero bounce back behaviors like described if they need initialization which is why I'm thinking that.
