Windshield Wiper Motor

I had an '83 Olds Delta Eighty-Eight Broughm which I finally sold several years ago after logging in 230K miles. I thought it had a bad windshield wiper motor then so I bought a new original equipment Delco wiper motor however, I found out all the problem was a loose connection. For anyone who still drive the Olds 88 or any Body by Fisher General Motor car such as Chevy or Cadillac, and has a need for this unit, it is for sale.
