The wiper motor was looking a little rough against the backdrop of the new
shiny insulation material, so I decided to clean it up. Taking it out was
no big deal once I understood how it was put together.

The wiper motor pushes and pulls a stiff cable. The cable runs to the
wiper arm pivots via a piece of pipe. The cable has a coil wrapped
around it so it can have a bit of friction with the wiper pivots as
it goes back and forth. This back and forth movement translates into the
wiper's movement. One must take the wiper arms off before removing
the motor and cable assembly.

The motor and cable come off by removing the nut that attaches the motor
to the pipe. After removing the wiper arms you can fairly easily pull the
motor and cable out. You may want to mark the position of the wiper arm
post before pulling it out. That way you can turn the post 180 degrees
so the contact point will be new and fresh after putting the cable back in.

A few assorted views of the motor/transmission/cable assembly. I noticed a
kind of slide adjustment on the motor near the power connector. Not sure
what it does. Maybe a travel adjustment.

Of course it could be different on other Interceptors, but the mounting
strap position on the picture below is way too low. With it set at this
location, the booster won't fit. The strap needs to be about 10 mm below
the top of the motor.
