Having windshield wiper/washer problems? Here are some more common problems.
The wiper motor is commonly replaced and was often not the problem. Don't replace the motor yet. maybe it's not the motor. It could be a fuse or something at the wiper switch. The wiper motor has two windings, fast and slow. The wiper switch sends a ground signal to each motor winding. More often, there are problems with the relay, or at the wiper switch, or in the cable to the motor.
Don't be too quick to replace the washer pump. The problem is often just a clog in the sprayer heads. You can clean out the sprayer holes with a needle, some have two holes, so look closely.
Hope this helps.
