Maxville Truck Posted August 24, 2007 Share Posted August 24, 2007 I've got a 1989 R model with a wiper motor problem..... It runs fine for a short while then it sticks the blades straight up and just leaks air...If you shut the switch off and then back on it will run again for a short time, the whole time t runs though it sounds like it is leaking excessive air out of the wiper's exhaust port... the motor is more of a round shape then the traditional barrel shaped motors i've seen on other trucks. Just wondering if anyone has any experience rebuilding these? any help would be apreciated, especially in kit sourcing!!
