One problem related to windshield wiper/washer motor has been reported for the 1999 Mitsubishi Montero Sport. The most recently reported issues are listed below.
The motor for my windshield wipers just suddenly went out. I am also upset that the parts store quoted me a price of $110, only to discover that it would be two weeks before one could be obtained, and then only Mitsubishi would sell it to me and for $190. Why would a motor go out on a vehicle with only 86,000 miles?.
