Unnecessary Power Window Switch Replacements – 2015-2017 Subaru Legacy & Outback

NUMBER: 07-93-15
DATE: 07/23/15

APPLICABILITY:	2015 MY and Later Legacy and Outback Models with Auto-Up / Down Power Window Feature
SUBJECT:	Unnecessary Power Window Switch Replacements

 

INTRODUCTION

This Service Information bulletin provides the procedure to follow when receiving a customer concern regarding operation of their power window Auto-Up and/or Auto-Down feature.  Testing of returned power window switch assemblies has revealed the vast majority are NOT failed as claimed.

 

SERVICE PROCEDURE / INFORMATION

IMPORTANT REMINDERS: 

• Whenever the vehicle battery is disconnected, the Auto-Up / Down feature becomes disabled. Although the switches will still control the windows, the one-touch “AUTO” feature will not function until the Initialization Procedure for BOTH front door power window switches has been performed successfully “resetting” the system. This feature is available on BOTH front windows on all Premium and Limited models. Only the 2.5i does not have this feature on the passenger front window.
• Always follow the complete Initialization Procedure outlined below BEFORE replacing any front door power window switch assemblies.

 

INITIALIZATION PROCEDURE:

STEP 1– Close the Driver’s door.

STEP 2– Switch the ignition to the “ON” position.

STEP 3– LIGHTLY press down on the driver’s door power window switch to lower the glass halfway down.

STEP 4 – Pull UP on the driver’s door power window switch and hold it to raise the glass until it is fully closed.  Continue to hold the switch UP for 1 second after the glass is completely closed.  Holding the switch this extra second is what the system needs to see for initialization to occur.

STEP 5 – Verify proper Auto Up / Down feature function.  If normal operation of the feature is not restored, the most likely cause is that the switch was held up for longer than the 1 second  as described in Step 4.  Repeat Steps 3 and 4 again.  If normal operation is still not restored, proceed with the diagnostic steps outlined in the applicable Service Manual.

STEP 6 (The following applies only to Premium and Limited models) – For vehicles equipped with the Auto Up / Down feature on the passenger front door, the Initialization Procedure will need to be performed on that door’s power window switch also.

REMINDER:  SOA strongly discourages the printing and/or local storage of service information as previously released information and electronic publications may be updated at any time.

Always refer to STIS for the latest service information before performing any repairs.
