maybe the washer pump is shorting out

i guess it would be easy enough to unplug for a day or two and see if the wipers come on without it

now its coming on like every five minutes even with the washer pump unplugged

probably the wiper turn signal switch on the column then or a short in the wiper motor. would have to test them to single out which is the cuplrit.
