Buy a new wiper arm at a dealer, buy a used wiper arm at a junkyard or on eBay. there is a spring in there which has a problem and it is easier to just replace the arm than fart around with that spring. note the arm will be the same on any big FMC model 98-02, but make sure your replacement is for the same side as the driver and passenger arms are generally not quite the same.

take the nut off the old arm, jiggle it up and off do not pry against the glass. before you take the old arm off put a piece of tape on the windshield along the top edge of the wiper blade to make sure you put the new one on in the same place.
