Thanks for the help, Huw. By golly, there was one, and
only one, of those 1/4 thermal protectors. The space
next to it is empty and not wired. Pulling it disabled
Looking further at the Mitchell schematics, I think I
am supposed to have only one thermal protector. It
feeds the control module for the windows which has a
lead out to the weld that feeds all the windows and
the sunroof. I still think I need to find that weld. I
will try to trace it from where the lead comes out of
the control module.
In the meantime, I have discovered that the aux relay
panel that I have does not resemble the one shown in
the Bentley or ETKA. They show a three row arrangement
with definite positions for each relay. There is also
a sticker on my knee plate that shows three rows.
However, mine only has two rows and the two that are
there are not arranged anything like any two rows
shown in Bentley, ETKA, or the sticker. Not sure if it
came from the factory that way or if someone really
got carried away rearranging it. It's an early build
89 100q, so maybe they were using up parts
transitioning from the 5000 to the 100 models?
Back to part of my original question, can anyone
explain why Bentley hasnt included the sunroof
