1963 Buick Riveria wiper motor

Recommended Posts

My 1963 riviera wiper motor and pump are not working.

since it is generally 55 years old I thought I would just replace it.

Much to my surprise reman wiper motors and pumps are very $$$$$$$$

does anyone know if a 1966 or up will work in a 1963?

 

RivNut has pointed me to ROA

I would exhaust all possibilities to repair the original motor.  What troubleshooting have you performed so far, and what were the results?

 

Start by looking at the Chassis manual to determine where there should be 12v power and test those locations with a lighted probe.

There is a switch inside the motor that controls the wiper parking operation.  It quits working.  It can be cleaned up and the motor will start to work again.  There are detailed drawings in the '63 shop manual of the motor.  Some of the drawings move the numbers around on the electrical contacts on the motor, to make the drawing simpler.  Look at the labels carefully.  Some are 1-2-3 and some are swapped around, like 1-3-2.  The drawings are correct for the points as labelled..

63riv425,

  Pay close attention to the wiper motor mounting bolts. One of the bolts captures a ground strap which provides a ground for the relay inside the motor. Try loosening and tightening the mounting bolts before completely removing/condemning the motor.

It's not a lite duty job to remove that piece, you might go a little slower before committing the motor is bad... slice in wiring, dash switch, fuse etc, Steve

To get to the wiper motor you usually have to remove the driver's side hood hinge and work blindly between the inner fender and the cowl.  As Steve says above, EXPLORE ALL OTHER OPTIONS FIRST!!!
