GT3 Automatic Window Step Down


Recommended Posts

I have a 2004 GT3 and my window step down or step back on opening or closing the door is not working correctly. The electric connection is made but the window only rolls down about 1/8th of an inch.

Any advice on how to repair this.

Mel

Mel:

If the GT3 has the same system as the 986's, 987's, 996's, & 997's, it sounds like your window regulator mechanism cable is stretched or getting frayed.

When that happens, the window will no longer retract the full distance required to clear the frame.

If you are getting the exact same result whether you pull on the outside door handle or pull on the inside door handle, then it is even more likely that it is the window regulator mechanism.

The customary repair is to replace the window regulator with a new unit. It's a fairly easy DIY repair, with the most difficult part being temoval of the door panel.

Search the archives and you'll be able to find good instructions on both the removal of the door panel and the replacement of the window regulator. If I can locate the links, I'll post them here.

One caveat: On 996's and 997's you must be sure to remove the bumper stop that usually comes pre-installed at the base of the front rail of the window regulator. If you don't, your window will not go all the way down.

Regards, Maurice.

Maurice,

Thanks for the advice.

I have the links and will try the fix.

Mel

would you post the links, I have the same problem with my right window, in my 99 carrera. thanks Halvin

Here is the link for door panel removal for a 996:

If I locate the other one that deals with the window regulator itself, I'll post it here, but it is pretty straightforward.

I ran across a post that I had written up with some useful tips for replacing the window regulator, so I thought I would post it here, in case you haven't found anything else:

If you have tried the window reset procedure already (it's in your maunal) it has not yielded any results, it's 99% sure that you must replace the window regulator to get that magic 1/2 inch drop.

It's a very straightforward procedure.

Four things to keep in mind:

1. Most of the oem replacement regulators come with a small plastic bag of parts that is contained inside the larger plastic bag which encases the regulator. That bag contains a small bump stop that must be attached to the higher of the two bottom square holes on the forwardmost leg (the lower bump stop is for 996/997).

2. Be sure to mark (with a sharpie or similar) the footprint of the old regulator legs where they sit on the bottom (horizontal) surface of the door. That will help you avoid having to later make an adjustment to get the glass in the proper plane (inboard to outboard slant adjustment).

3. Raise the window almost to its uppermost position so that you can access the two torx screws (that must be loosened to release the glass window from its clamping brackets) through the hole provided for that purpose. One in front, one towards the rear, covered by black rubber plugs.

4. Do not clean the two areas near the bottom of each glass window where the clamping brackets are attached to the window. You can use the "dirt marks" as one of the guides as to where the window should be re-attached to the new regulator clamping brackets. The other guide is the forward bottom angled corner of the glass.

Regards, Maurice.
