I recently bought a 1991 Ford F150 and had a couple questions. How do you remove the Gear and Rod that hooks to the motor and then to the wiper arms. I didnt want to pry on them becuase Im not sure how the rod slides out. I need to get these out so I can clean the rod. Truck has sat awhile and has corroded on the rod making it noisy and slower. Second I have a bad automatic door Window Switch. After looking I see its almost impossible to get to the motor. Whats the easiest way to check the motor or remove it.
