I had the same problem with my 92 Grand Marquis. Seems that the windshield wiper motor was running in the opposite direction for one reason or another. You may need to replace the motor or have someone look at it. Fortunately for me, my mechanic drilled a hold on the motor and flipped around, now my windshield wipers stay down when not being used, however they stay up when in use... weird.
