What are the general steps in removing and replacing the linkage (and possibly motor) in a '66? Should I just sell it and buy another car?

 

What is the problem you are having?

 

It has to do with the movement of the wiper arms. The passenger side moves properly, smooth etc. HOWEVER, they usually do not want to turn off! I will turn the switch off, the wipers will reach the bottom of their stroke, but the driver's side manages to awkwardly bump back up. This causes (I assume) the wipers to go past the power cutoff point and just restart their rotation again. I assume it has to do with the linkage, not allowing the driver's side arm to make the proper movement. I replaced the wiper switch about a year ago. ~~Does this make sense?

They will not turn off with the engine above idle. I usually need to have the car not moving, in gear, with the electric fan and headlights on in order to draw enough power away so they will turn off. Huge headache.

 

Move to Seattle...... Problem solved.

 

Doing the wipers is a PITA but it does sound like you are on the right track. I would think the motor needs replaced if they will not park correctly.

 

Should I try the motor first? I assume that job is easier than the linkage, how tough is the linkage to install?

 

I replaced the linkage on a 65 Mustang that is the middle of being rebuilt so everything behind the dash was already out (radio, heater box and controls, dash pad..) The instrament cluster was also pulled out. There are three screws that attach each transmission arm to the underside of the cowl and there are spring clips that hold each arm to the motor shaft. With the guts out, it was not difficult. I am still installing the "guts" so will have to see how the defrost ducts pass the arms.

 

I just went from 1 speed to 2 speed wipers in mine while we were rewiring the car, and its not that difficult. Having the driver seat out and the instrument cluster out is the only way do do this if you ask me.
