When I got the car at 80k miles last summer they weren't working. A couple days later after having the heat on blast they started working again. Every now and then when it rains the wipers stop working but eventually I can turn them on. This time after having the car for a year they stopped working completely. What needs to be replaced?
My windshield wipers dont work on 2004 Pontiac Grand Am
Hard to say, you'll need to perform a diagnosis. Check for power and ground signals to the wiper motor and go from there.
