Odd problem with my 93 Taurus LX 3.8L, 160,000 miles.
The wipers work fine at low and high. But when I try to use any of the
delay settings, every time the wiper pauses (for whatever time the delay
is set) on the upstroke pretty much right in the middle of the windshield
(not the same exact spot every time). After the first pause when it
reaches the top of the travel, it pauses yet again.
It never pauses on the down stroke.
Any ideas on the likely cause of the problem?
