If you are still on line I removed wiper module my part number is17d539-ca. Do you know why the number is XXXXX? this truck was made in march of 94,that does make a diference,every time I get parts they ask me the month. Sounds like I am talking about a model T,doesnt it. LOL
The number you are seeing on the module is an engineering number. The part number on your veihcle has been supperceeded to the number I gave you. The old number was F4TZ-17C676-AA
What is the first part of that number on your module anyway? I can run another check and make sure it matches.
