well its been raining lately and i've been finding a prob with my windshield wipers, like they will go fine the first time but then when the wipers try and go to the second time and they stall and stick. then when they get back down and i wait a few extra seconds they work fine. but everytime i try and just let them go for more than one wipe then they stick. what do you think? would it be the motor? or what? and where and how can i get to the motor?
