wiper door vac canister
Is there any way to test the wiper door vacuum canister without a vacuum source? Motor is not in car yet and I do not have any kind of vacuum pump. I cannot push or pull rod/bolt that exits out the back by hand. It's out of a 69 BB car.

You might find another car to use as a test donor for vacuum...
If the actuator holds vacuum on the back side, the diaphragm inside is good. if it leaks on the backside, then you need an actuator.
If it leaks on the front but no on the backside, you need to replace the shaft seal.
This picture is for headlamp actuators but it's the exact same for the wiper door actuator.

I don.t think the canister itself could freeze up to the point the shaft will not move. If you remove the canister from the mount, I think you will find that it is actually the wiper linkage itself that is frozen.
With the canister off of the car, put a finger on the hose nipple opposite the shaft and if the shaft moves (provided the plug is solid if it is the later pie pan style) the diaphram is bad.
Cover the nipple on the shaft side and if the shaft moves, provided the last test indicates the diaphram is good, the shaft seal is shot as Wilcox said.

You have the early or late design? You'll have to measure the shaft size to see, but early was 1/4" shaft, late used 5/16" shaft.

How long is yours ?
1969 BB car. Wiper actuator on firewall has a shaft going through firewall. That shaft connects to a "wiper door actuator rod nut". That in turn is connected to a "link" that pivots. My "link" may have been broke off short at one time. I only have about 4 threads left on it. That's enough to thread onto the rod nut but may be too short. Anybody know how long or maybe just how many threads are on a good link? I just don't want to buy one if this one is the correct length. Thanks

Are there any rebuild kits for the kick panel door (would need the small rivets and the rubber seal)?
