Martin,

I'd bet money on corrosion between the wiper shaft and the bushing.   I had
one motor burn out after same symptom (replaced under warrenty), and pulled
and rehab'ed the most recent one on our 87  after it started getting very
slow.   I removed the whole assembly and with WD40 worked the shaft out of
the bushing, then used 600 grit emery cloth to clean the corrosion off.
I let the WD 40 evaporate and then saturated the bushing with oil and
covered the shaft with light grease.   No problems in three years, but I've
also been very careful to put a drop of oil on the shaft at the bushing
every month since then (you need to remove the arm and pull the plastic
cover off.)
