Rectification of Driver's Side Power Window Switch in Singapore


Special Service Campaign for POWER WINDOW MASTER SWITCH (BMS)
 
Official Statement:
 
Following the announcement made by Toyota Motor Corp in Japan on 10 October 2012, Borneo Motors Singapore will initiate a Special Service Campaign for select Toyota Yaris, Vios, Corolla Altis, Camry and RAV 4 models.
This campaign is to rectify the condition that may cause the drivers’ side Power Window Master Switch to experience “notchy” or “sticking” condition when in use. This is a proactive measure Toyota is taking to ensure attempts to rectify this condition is carried out with Toyota approved method and the appropriate lubricant.
 
At the moment, we are still pending further clarifications specific to the involved Toyota models distributed and sold by Borneo Motors.

The Power Window Master Switch may experience a “notchy” or “sticking” condition when in use.
If commercially available lubricants are applied in an attempt to address this condition, the switch assembly may overheat and melt.


 
Q2: What is the cause of this condition & concern?

This notchy or sticking condition may be caused by uneven application of grease lubricant at the original supplier of the switch. As such, over time and with frequent usage, the contact points within the switch may deteriorate prematurely, causing the “notchy” or sticking condition when in use.

If owners attempt to use commercially available lubricants, the resin or plastic parts inside the switch may become overheated by ingredients in these lubricants and melt.



Q3: What brand of these commercially available lubricants is likely to cause this condition?

We currently do not have this information.
 
 

Q4: Which models and how many vehicles are involved?


In Singapore, the models involved in this campaign are
Camry, Corolla Altis, RAV 4, Vios, Yaris – models produced between February 2006 and April 2009.
Approximately 15,000 units may be involved. However, we are in the midst of verifying the actual involved units locally.
