I have a problem with my 1985 380SE. The nut that holds down one of the
wiper arms onto the wiper transmission has worked itself such that it spins
in place. That is, I can't get the nut off, but it's not stuck either.
Something has stripped in such a way that the nut is just stuck there. I
can't for the life of me see a way to get that nut off without damaging the
wiper arm beyond repair. I do have a dremel, but a cutting wheel can't do
the job thats to the shroud of the wiper arm around the nut. Any ideas on
how to get that damn nut off?
