Circuit Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
- A signal from the windshield wiper switch is sent through the column-ECU inside the column switch to the front-ECU. The signal turns on the relay inside the front-ECU to operate the windshield wiper motor.
- If the SWS communication line is defective, another signal line (wiper back-up circuit) will be active. In that case, the windshield wiper will operate at low-speed when the windshield wiper switch is in the "LO" or "HIGH" position.
