So first of all i have a 2005 base grand prix ... 2 weeks ago the wipper start to run slowly , sometime i have to help it to park . Now they dont work at all no sound no move ... the motor? the wipper transmition? what do you think ?
Update: The problem was the little rod where the wiper is attached , sand,dust and mud come between the rod and the transmission arm and rust here . Pull off the rod , clean and grind the rust in the hole and on the rod, apply some grease (mmmmm lot of grease) and the wiper work like new!
