1. Remove cover A from rain/auto light sensor B.
2. Disconnect the 5P connector C from the rain sensor/auto light switch.
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 checks are positive, replace the rain/auto light sensor.
