1. Remove the bottom of the control panel.
2. Disconnect the 6P connector A from the headlight washer control unit B.
3. Check the socket and connector terminals to make sure they are making good contact.
If the terminals are bent, loose, or corroded, correct them and recheck the connections.
If the terminals are OK, go to step 4.
4. Without connecting the connector, run these checks on the connector inputs.
If any test indicates a malfunction, find and eliminate the cause and repeat the test.
If the input test is positive, replace the headlight washer control module.
