There is a rubber fitting under the sill on the wheel box just like there is on 
top. These rubber parts deteriorate over time and can crack. Im guessing that 
is what has happened to yours. Its a fairly easy thing to replace.

After much effort, I got the wiper motor and switch working as they should.

Ed, a list member, sent me the following information:
The green wire is always connected to 12V, thru the fuse of course.
For High Speed, ground the R/LG wire.
For Low Speed, ground the R/LG wire and the N/LG wire.
That is the way it works in the TR250.  It sounds like other Triumphs do 
it differently.

But now, I have discovered a new problem - isn't that the way it always 
goes!

The passenger wheel box assembly wobbles when the wiper is running. It 
wobbles less when the windshield is wet, but it still wobbles.

I have tightened the nut as much as I dare - it helped, but it still 
wobbles.


The first thing I did in this process was to pull the wiper rack cable 
out, cleaned and greased it and put it back in.  I did not do anything 
to the wheelboxes, thinking the grease on cable would take care of the 
wheel boxes.


Do I need to get new wheelbox fittings?  Will that help?  Is there 
anything else that holds them in place?

Thanks,
Roger
