I know I have quite the number of questions but I definatly figure you guys know best. So here's the low down. Sometimes when I goto turn on my wipers they only budge a 1/4 inch or so and don't go, turn them off, then back on still nothing, then just randomly they'll start going. Other times they'll go but they will struggle and move very jerkily( new word) and sometimes they just stop halfway up or down. Please oh please tell me its something less costly then getting a new wiper motor.
