Window will not move when door opens/closes

[Mr. Balls]

I have a problem with the passenger side window on my 99 Boxster. Normally when you pull up on the door handle the window will lower as you open the door and then raise back up to create a tight seal when you close the door. Right now when you pull the door handle you can hear it sound like it is trying to lower the window but it won't actually do it. Like if you gently pull the handle, not enough to open the door, you can hear the motor kick in and you will see the window act like it wants to move but won't. I took the panel off the door today and couldn't really find anything wrong except that there seemed to be a significant amount of play on the front cable. The rear cable seems very tight with no play. Take a look at this picture, this is when the window is fully raised:

The window raises and lowers fine with no problems at all from the switch however what does seem to be strange is that when the door is open, if you raise the windows to maximum it will go all the way up to the level the window is supposed to be at when the door is closed. Usually when the door is open it is only supposed to raise so high and not raise that extra 1/2" to create the seal until the door is closed.

I haven't made any adjustments to anything and not really sure if that will help anyways. Up until yesterday it seemed to be working fine. Any suggestions or ideas would be appreciated.

After doing a little research it looks like it would be a window regulator issue and that it will need to be replaced. Apparently, from what I have found, you can't adjust the cables. Anyone have any input?

Your research is correct. Adjusting or "shortening" a stretched cable has not been successfully done, AFAIK.

Most practical solution is to replace the window regulator.

There are a number of threads here addressing this particular issue, including two that show attempted repairs to some of the window regulator mechanism parts, but none that involve reducing the length of the cable.
