embarassing child lock question

[Colin Weir]

Hey,

Today, I decided to make some progress on the non-functioning rear
window switches in my '85 4kq. After much effort, I finally found the
leverage point to remove the switches from the trim plate. Following
instructions on Huw's website, I removed the connectors, and carried
the switch inside. I pried off the switch cover and expected to see
two cylinders resting on top of two small ball bearings. My switches
were different, with the rocker switch resting on two plastic
squares, resting upright and sitting on a bit of the switch below. I
could not make out exactly where the contact should be taking place.
In fact, the switch looked like it broke contact when it was
activated. At any rate, I used a sharp pointy thing to clean some of
the carbon looking stuff in the switch. I also cleaned off one of the
exterior contacts which looked like it had some dirt on it. The
switch went back together easily, and fit back into place with no
difficulty. I started the car, deep breath and...the window went down
halfway, up back into place. Then nothing. switch ceased to work
again. Strange. So I think, maybe the child safety switch is engaged.
I push on it, and it moves, but made no clicking sound at all. I
could not tell if it was actually engaging or disengaging. I pushed a
little harder, and all of a sudden the child safety switch popped
underneath the trim plate. I think to myself, oh well, I'll just pop
it back in. But the switch is NOWHERE to be found. I searched
underneath the plate with my fingers and looked with a flashlight,
but I cannot find the switch anywhere. I figured that the switch
would be connected to some sort of wiring underneath, but I checked
every wire and could not locate it.

1. I was hoping someone would be able to suggest what the child
safety switch should be connected to, so I can try and dig it out
from wherever it is.

2. If anyone has any BTDT on cleaning the type of switch I am working
with, that would be helpful. As a note, I switched a working switch
onto each of the rear windows and they opened and closed without
difficulty.

Thanks for your help.
