Check that the intermittent wiper interval is changed as the windshield intermittent wiper volume is operated.
Turn the windshield intermittent wiper switch to the intermittent operation position. Use the M.U.T.-III to set a simulated vehicle speed with the wiper volume held. The intermittent wiper interval should be changed as the simulated vehicle speed is changed.
If either of above is defective, carry out the troubleshooting. (Refer to )
