master window switch will roll down but not up passenger window help!
info:
1990 ls400
ALL power windows work on their own switch
problem:
master (driver) window switch rolls all windows down and up fine
EXCEPT for passenger REAR window.
the master driver window switch will roll the passenger REAR window down BUT not up.
ive searched
and best thing ive came up with was from the GS forums where they say go to each door and roll down the window all the way then roll it up completely
a master window switch can get a dirty contact internally, and can be taken apart and cleaned, but I would only do this if you are good at small meticulous things - like the kind of guy who can replace a screen in a smartphone, for example.
