As far as testing goes before you start replacing/rebuilding stuff, also make sure that there isn't a problem with the linkage itself. You'll need to disconnect the wiper linkage from the motor to do this. Once it's disconnected, move the wipers through a full sweep. They should move pretty evenly and smoothly.

The pump by itself, not connected to the intake, should draw about 19" of vacuum. Ken Quoting tom jennings<tomj@xxxxxxx>:yeah, what joe sez. pull the hoses off it, run the engine, stick your finger over each port. one should suck your finger to it, hard. if neither does pump is bust. if one does, that goes to the wipers, the other to the manifold. unless the hoses are new they are certainly all bad and leaky.

You want the inlet side of the vacuum pump connected to the wiper motor. You can verify that it is creating suction by using a vacuum gauge or even justunpluggingthe line at the pump or the motor and verifying that there is good suction. The wiper motors fail with age due to dried grease in the mechanism andflapperdiaphragms which age and do not seal to the motor case. They can be rebuilt.

They move slightly when turned on, but lack enough strength to move the blades more than a few inches. I am assuming I need to pull the heater box and rebuild the vacuum motor, but before I do that I thought I would check the obvious.Thevacuum lines look good, but I have a question about the hook-up of the vacuum booster fuel pump. Which fuel pump port should be connected to the manifold and which to the wiper motor? When I look down at the top of my fuel pump, the line from the manifold connects to the port on the passenger side of the pump while the wiper motor hoseisconnected to the port on the drivers side. They cross over each other, which doesn't really make sense to me. Is mine hooked up like yours or is it backwards? FYI, I have the 196 cast iron engine. If some members with similiar cars could look at their set up and conform my set up I will be a happy guy. Thanksinadvance. Mike Klepp
