I took the wiper motor out of my 54 3100 and lubed it up good trying to get them to work again. Motor worked real good sitting on the fender.. put it back together and it still cycled to the windshield edge and quit.
Took my daily 15/20 mile ride today when out of the blue they started working like a goose getting airborne at the pond... FopFopFopFopFopFop! Weren't working as they should but working non the less. Back to the shop.
Come to find out that the trans arm was hanging up on the repop defroster vent seam. A sharp wood chisel carved out the offending plastic and now they work like new. Hallelujah! Saved me a bunch of bucks replacing the motor!
I'm stoked!
Jethro.
