Hello my name is XXXXX XXXXX X will be more than happy to assist you.
There is two parts that normally go bad the could cuase the same problem. The wiper motor switch and the wiper control module.
To verify which one what you will need to do is:
Do the wipers park?
If they do replace the wiper/washer switch.
If they don't replace the wiper motor module.
Connector is located under the dash by the steering column.
