Deletion of Compass Mirror – 2013-2014 Subaru Legacy & Outback

NUMBER: 15-156-12R
DATE: 08/20/12
REVISED: 11/19/14

APPLICABILITY: 2013-2014MY Legacy and Outback Models with Backup Camera
SUBJECT: Deletion of Compass Mirror



2013 Model Year Outback and Legacy vehicles equipped with a backup camera no longer have a compass feature available in the factory installed auto-dimming mirror. In the event a customer requires a compass feature in an auto-dimming mirror, the factory installed mirror on some trim levels may be replaced with an auto-dimming compass mirror with HomeLink.  This mirror is different from our standard accessory mirror offered for 2013 Outback and Legacy vehicles. Please reference the following chart for applicability and part numbers. Installation of the HomeLink mirror should be treated as any other accessory installation request by the customer and is not a matter for warranty.

Warning: There is no accessory mirror that can be installed in vehicles equipped with EyeSight. The OE mirror on an EyeSight vehicle should not be modified or extended.

The service procedure involves removal of a toothed washer and replacing it with a spring wave washer.


Countermeasures for Frozen Power Windows – 2013-2014 Subaru BRZ

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

SUBJECT: Countermeasures for Frozen Power Windows



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.
