20140920VISIBILITY/WIPER
THE HEADLIGHTS DID NOT COME ON AUTOMATICALLY WHEN THE VEHICLE WAS STARTED; IT WAS AFTER 9 PM AND COMPLETELY DARK. THE HEADLIGHTS WOULD NOT COME ON EVEN WHEN THE SWITCH WAS USED. I HAD TO DRIVE HOME USING THE HIGH BEAMS. THE HEADLIGHTS DID COME ON AFTER I HAD GOTTEN HOME, TURNED THE VEHICLE OFF, WAITED APPROXIMATELY 15 MINUTES, AND THEN STARTED IT AGAIN. THIS HAS OCCURRED MULTIPLE TIMES. ON A SEPARATE OCCASION, DURING A HEAVY DOWNPOUR IN RUSH HOUR TRAFFIC THE WINDSHIELD WIPERS STOPPED WORKING. I WAS ABLE TO GET OFF THE HIGHWAY AND PARK TO WAIT OUT THE RAIN. I TURNED THE VEHICLE OFF AND WAITED ABOUT 20 MINUTES. THE WIPERS BEGAN WORKING AT THAT TIME. THIS LAST ISSUE HAS NOW OCCURRED TWICE. I HAVE PARKED, TURNED OFF THE ENGINE AND GONE INSIDE THE STORE FOR LESS THAN 5 MINUTES. WHEN I TRY TO START THE ENGINE, IT WILL NOT TURN OVER (NO SOUND AT ALL). I TURN THE RADIO OFF, WAIT A MINUTE OR TWO, AND THEN WHEN I TRY AGAIN; IT STARTS AS IF THERE WASN'T EVER AN ISSUE. *TR
