Front Wipers Problem

Greetings!!!! My 98 Expedition has a space cadet for an owner. He left the driver side window open overnight and it rained. Next morning, when he started the vehicle the front wipers came on (intermitent speed). He thought that the water might have shorted the control and that once dried, everything would go back to normal. That has not happened yet (three days later). Any suggestions on how this air head can resolve this problem? Thanks in advance for your comments.

IT'S A MIRACLE!!! I got up Saturday morning with the intent to work on my wipers and long and behold, they were working fine. I guess moisture had shorted the switch and when it dried all went back to normal. THanks for the attention :smile:
