now im confused.. my average mpg before toyota had the car was 1st bar falls off at around 110km, 2nd bar 190-200km... after toyota my km was 165km n 2nd bar was gone.. and my average is 175 km for that 2nd bar to fall off.. but over all my mpg is the same for the whole tank. toyota must have done something >> but for now i dont really care..

This is a picture of a burnt one from an article on repairing them (http://www.toyotawiki.org/index.php?...indow_switches):

Attachment 48768



Basically the switches are switching high current (~10 Amps) to the power window motors. They are directly doing the switching, rather than switching the coil on a relay (as is done with most of the other high-current switching on a vehicle). So, if the contacts are coated with something that is conductive or becomes conductive over time (the carbonization mentioned in the recall article), current flowing through the resistive (partially conductive) material will make it heat up. With the power windows being fused with a single 30A fuse, you have the potential to create up to a 420 Watt heater (14 Volts x 30 Amps) before the fuse blows.

I've repaired switches like these since I worked for Volvo in the 80s.
The carbon is NON conductive, thats why the switches stop working.
Wiping off the NON conductive carbon, allows the switch to contact.

BTW Pretty much all window switches do this wether they use a relay or not..

The grease used in Toyota switches become carbonized, and conductive.

And what does this idiotic statement have to do with the 7.4 million Toyotas worldwide that are being recalled?

Carbon is conductive and generates a great deal of heat when current is run through it, hence carbon-arc lighting or carbon-arc welding.

Did you miss the memo that the Yaris/Belta/Vios/Vitz are manufactured and assembled in Japan?

This is why I like cranks and manual locks. There are less moving parts and components to malfunction, break, or wear out.

I didn't buy a Hyundai because none of them came with crank windows or used real non-electronic keys to unlock the doors. I'm so glad I held out for the old trailing edge technology.

Right ALL power window switches do this. So ONE incident triggers a recall costing millions which does NOTHING to improve safety.

Ha Ha ... I am sure there are 2 people here on YW that are saying "I told you so" re this recall. I am still a fan of power windows, this doesn't change anything for me.

...more than two....but definitely fewer than fifteen....so, you're right, not very many.
