[xj-s] Wiper Motors

Hi All,

I'm fairly new to the list, so I don't know if anyone has posted a similar
repair before or not.  If it's old news, I'm sorry, just delete it.

With my '85 XJ-S, I've had the problem a couple of times with the wiper motor
failing from water intrusion.  The first time, I bought a new unit ($475).
The second time, I tore it apart and repaired it.  After the repair, I sealed
the motor with RTV to keep water out.  I was surprised when last week, the
wipers quit again.

I took the motor apart and found that one of the magnets had come loose and
had jammed the armature.  The magnets are glued in with what seems to be some
kind of silicone.  Rust had crept under the bond and it gave up.  I marked the
location of the magnets with a file and measured the distance from the end of
the housing to the top of the magnet, so I could put them back in the correct
position.  I also marked the magnets as to their location and orientation.  If
they're put in wrong, the motor will either run backwards or lock up.  I then
removed the magnets and cleaned them and the inside of the motor housing with
a sanding flapper wheel in a drill motor.  I then mixed up some JB Weld and
glued them back in place.  Once cured, I painted it with rustoleum to prevent
further rust, and put it back together.  Works great and should last a long
time.

Now the sad part.  I was in the process of doing the same repair on my "spare"
motor and dropped one of the magnets onto the garage floor.  It shattered.
So, if anyone has a  dead motor I could get a magnet out of and want to get
rid of it cheap, drop me a note.
