How to keep wiper door open?
Okay, so I need to replace my wiper door canister on my 72 and will be ordering a new one very soon - the wiper door shuts fine but takes a long time to open, if it does at all. In the meantime, I plan on manually opening the wiper door when I need it - the problem is that the door shuts as soon as I turn off the wipers. How can I prevent this? Using the **** under the steering column didn't help this specific situation - can I just disconnect and plug the vacuum line?

While you are waiting to replace the cannister.....disconnect both vacuum lines from the cannister (front and rear).....plug the lines.
Now you can open and close the door by hand....it will stay where you put it. Those cans are easy to rebuild....just order the rubber parts...clean and paint the can or just shine it up.
Good luck.....

Are you using the correct "****"?
The large round **** (whihc turns) stops the wipers on the windshield so you can change them.
The other two switches on each side of the round **** keep the wiper door or the headlight doors in the open position depending on which one of the two switches you pull straight down.

I believe it has a vacuum relay that switches to "open" or "close"
ports on the actuator ... just like headlights.
So, take the vacuum feed into the vacuum relay and connect
directly to "open" or "close" port ... depending on your weather.
If spring assisted to close, then this (I think any) technique
will not work.
In this case, you might be able to wedge a piece if packing foam
or wood such that the linkage is held open.
Based on Fotyfobravo response, my first suggestion should work to keep door open (or closed).

One more thing. I noticed that you said it works fine in one direction. That tells me that the inner diaphram is good and ONE of the rubber endcaps are bad. I bet you just need to order new rubber caps for both ends. Clean it up ...should work fine.
