How to Replace a Windshield Wiper Module

The windshield wiper module, or governor, controls the wiper motor operation. The module receives input from the wiper switch, and in some cases from various sensors as well. It is responsible for determining wiper speed and parking. A faulty windshield wiper module can result in erratic wiper operation or wipers that don’t work at all. If your windshield wiper module is on the fritz, it’s important to replace it immediately.
