I can hear the motor when I turn them on but they won‘t turn. What‘s the problem ?
The motor push/pulls rods that connect to the wipers under a cover called the valance, it's the part with the louvers in it. You can reach the wipers from the firewall, there will be some sort of lock mechanism to hold the rods on, take cell phone photos, from several angles, of the wiper pin to an auto store and ask for whatever holds it on. Tell him the problem. It is very fulfilling to fix your own car if you're not a pro mechanic.
