Countermeasures for Frozen Power Windows – 2013-2014 Subaru BRZ

NUMBER: 07-79-13R
DATE: 10/30/13
REVISED: 01/28/14

APPLICABILITY: 2013-14MY BRZ
SUBJECT: Countermeasures for Frozen Power Windows

 

INTRODUCTION

This bulletin provides information for 3 countermeasures to address concerns regarding power window operation during cold weather when the door glass may become frozen to the outer weatherstrip.  The customer complaint(s) may be: the indexing feature (door glass drops slightly when opening door) was inoperative, window(s) were inoperative, or the window switches were blinking (indicates a need to reset the index function).

  • A revised, hallow-type outer weatherstrip is used if the nap (fuzzy) portion has been pulled away from the rubber after freezing to the outside of the door glass.
  • A change has been made to both of the power window switches which decreases the distance (stroke) of when the door glass lowers from 20mm to 10mm during the indexing function. The indexing function is controlled by an input from the outer door handle to the BIU which lowers the door glass slightly to clear the drip rail.
  • A change has been made to “guide door lifter” to prevent a rattling noise which may occur as a result of the decreased index function door glass stroke.

NOTE:  See the Appendix at the end of this bulletin for information on resetting the indexing function should it become inoperative.
