1997 Mitsubishi Mirage

EVERY TIME IT RAINS, I MUST USE WINDSHIELD WIPERS, BUT THEY FAIL TO WORK AT ALL SOMETIMES--ABOUT 50% OF THE ATTEMPTS, AND DO NOT WORK WELL ENOUGH THE OTHER 50% OF THE TIME. I HAVE DISCOVERED THAT I CAN STOP THE CAR, LEAVING THE CAR ON, AND 'EXERCISE' THE WIPERS TO GET THEM TO WORK BETTER. I TOOK THE CAR IN TO THE DEALERSHIP, BUT THEY WERE UNSUCCESSFUL WITH PINPOINTING THE PROBLEM. THE WIPERS HAPPENED TO HAVE BEGUN WORKING, AS IS THE COMMOM OCCURRENCE; SO THAT WAS GOOD ENOUGH FOR THEM. IT IS EXTREMELY FIGHTENING TO BE DRIVING ALONG THE INTERSTATE AND HAVE THE WIPERS STOP WORKING! THAT HAS HAPPENED MANY TIME--INCLUDING ON TRIPS. THE DEALERSHIP WAS WILLING TO TRY A $90.00 SWITCH AND IF THAT DID NOT WORK , THEY WOULD HAVE REPLACED THE MOTOR FOR OVER $300.00 MORE. THEY REFUSED TO GUARANTEE LOCATING AND FIXING THE PROBLEM FOR THAT AMOUNT OF MONEY--PLUS LABOR, OF COURSE. SO, THE PROBLEM JUST REMAINS. I HAVE ESTIMATED THE DATE THAT THE PROBLEM FIRST BEGAN BECAUSE I HAD BEEN DEALING WITH IT SINCE THE BEGINNING OF HAVING THIS CAR. THAT DATE IS AN ESTIMATED TIME OF WHEN I TOOK THE CAR TO THE DEALERSHIP ABOUT THIS PROBLEM. AS WELL, THE NUMBER OF OCCURRENCES IS AN ESTIMATE. I DON'T KNOW HOW MANY TIMES IT HAS OCCURRED. IT OCCURS EVERY TIME I USE THE WIPER SYSTEM. I ASKED THE DEALERSHIP IF OTHERS HAD REPORTED PROBLEMS WITH WIPER SYSTEMS OF MITSUBISHI MIRAGES; I RECEIVED NO ANSWER. I WOULD LIKE TO RECEIVE HELP IN FINDING SOMEONE WHO CAN REPAIR THIS PROBLEM. I WONDER IF THE DEALERSHIP IS REQUIRED TO REPAIR A PROBLEM SUCH AS THIS. WOULD A WIPER SYSTEM FAILURE PROBLEM BE CONSIDERED A SERIOUS PROBLEM? I HOPE SO SINCE BEING ABLE TO SEE IS VITAL TO THE DRIVING SITUATION. I KNOW THAT WHENEVER THE WIPERS STOP, I HAVE TO FIND A WAY TO PULL OFF THE ROAD WITHOUT CAUSING AN ACCIDENT IN THE PROCESS OF IT AND DESPITE THE FACT THAT I CAN NO LONGER SEE THE ROAD AT ALL. IF YOUR DEPARTMENT CAN HELP ME, PLEASE CALL OR EMAIL ME. THANK YOU FOR HEARING MY ISSUE.*AK
