Defender wipers blowing fuses

I have a Defender 90 300Tdi M reg.Suddenly over the weekend (very foul
and wet) it started blowing wiper fuses.The rear wiper fuse 15A
(twinned with the indicators) blew 3 times (Not instantly - it worked
for a while but eventually went again).The front wiper fuse 10A blew
once but has been ok till now after replacement.
Has anyone had similar experience or can suggest what the cause of
this strange behaviour could be.Suggestions for tests I could do to
throw light on the matter also very welcome.
Many thanks in advance.

the rear motor lump can get crudded up and stiff.

Thanks for the advice.I have now taken off the cover (6 little torx
bolts) of the rear wiper crank mechanism and it's clean as a whistle.
Having then replaced the fuse again,I ran the rear wiper motor (with
arm/blade removed) for over an hour and nothing untoward happened.
It's not now pxssing down and I don't know whether that was a
significant factor?
The other possibility is that it was caused by an indicator fault
(with which the rear wiper shares a fuse).Any thoughts on how winkers
could cause fuses to blow after a while (not instantly) either in the
wet or dry?
All thoughts gratefully received.
