SUBJECT:
Additional Window Stops
MODELS:
E30 Convertibles
Situation:
Beginning with approximately May 91 production, E30 convertibles have had an additional window stop installed to limit upward travel. This additional stop consists of a fixed piece fastened to the inner door skin and an adjustable stop screw fastened to the window regulator arm.
Adjustment of the stop is accomplished by lowering the window completely and turning the adjustable stop screw. The stop screw is accessed by removing the center plastic plug in the bottom of the door.
Please note that the original stop (accessible behind the plastic cover in the inner door panel) is still installed and must also be adjusted.
The new style stop can be installed on earlier cars if necessary in case the original stop becomes ineffective due to wear or stripping of the threads from over tightening. Please follow the installation instructions.
Warranty Status:
Covered under the terms of the BMW New Car Limited Warranty.
