1998 Rodeo The front wiper fuse blows after a few swipes, and only when it is raining... no joke I have tried them with a fresh fuse when dry and they will work forever, when it begins to rain... "pop goes the fuse".

Any thoughts????

Only thing that comes to mind is a failing wiper motor that is occationally over-amping & blowing the fuse.
