Passenger automatic window light stays on after vehicle is shut off - 2002 Sequoia Limited

Hello,


I am chasing down a parasitic draw on my battery and I have narrowed it down to the ECU-B fuse which unfortunately has a lot of things that connect to it.

I eventually noticed that the light on the passengers automatic window switch (on both the drivers and passengers side) remains dimly lit after the vehicle is turned off - you can't really see it unless it is dark. The only way to get it to go off is by pulling the ECU-B fuse.

The passenger automatic window switch otherwise operates normally. I've done the automatic window "reset" thing which does not help.

The drivers side automatic window switch light goes out as expected after the vehicle is shut off.


Anyone seen this before or know where the fault might be ?


Thanks

 

I just checked mine (04 limited Sequoia).
There is a relay that I hear behind the dash drop out 10-15 seconds after shutting the vehicle off. That's when all 3 driver/passenger auto window switch lights go out.

Not sure if that helps but if you can find the window switch light relay, that should be your issue.

 

Thanks for the quick reply. The drivers auto window light does go out as expected but the two passenger auto window lights remain on indefinitely, so I think its something local to the passenger side circuitry.

 

Not a problem.
Yeah, you're probably right if the relay is working for the drivers switch. Do you hear it drop out?
Without seeing a wiring diagram I would pull the switch assembly on the drivers side to see if there is anything obvious.

 

I realize this is a sequoia, but maybe these can help to get an idea?

Thanks! I will have a look.
