1. Turn the ignition switch and headlight switch to ON, and confirm that the headlight washer operates with front wiper washer switch pressed ON for 0.6 seconds (approx. 1 second).
NOTE:
If the front wiper washer switch is released to OFF within 0.6 seconds, headlight washer will not operate.
2. If the headlight washer does not operate, check the headlight washer system harness and repair it if necessary. 
3. If there are no problems on the harness, replace the headlight washer timer.
