How is this possible? A tiltaway question
 
I had question earlier on the location of the vacuum canister and it looks like its missing and the hoses have been cut. Its a 1969 Mach 1.

But! This is interesting, while I was working on the door and at the same time letting it idle (I had it die on me in traffic when it was idling so I was trying to see how to replicate it),

Well shut the engine off with the door open and the steering wheel immediately swung away! It won't do it with the door closed and the ignition shut off.

So how is the vacuum actuator working without a vacuum reservoir? Is it some getting vacuum constantly with engine running and loses it as soon engine shut off?

Anybody have any ideas? It spooked me when I shut the car off and that wheel slammed up..lol.

Thanks!

Any Ideas ?

Must just be possessed ;) Don't be mean to it in the future or it might come back and getcha...

Yeh that's kinda what I was thinking..lol. I'll have to make sure that I treat this car nice...I don't need another Christine...haha :skullnbones:

The tilt away should work that when you shut of the car and then open the door the steering should tilt away. It should like your system is wired into and switched source of power (key on). If you wire it into and constant source of power (power all the time)it should work as designed.

Right, but if he has no vacuum canister to prompt the swingaway feature, I wouldn't think that it should work!

As the "owner" of a possessed car, I can sympathize :lol: I have yet to figure out how to escape. The good news is that the car isn't quite murderous, just extremely rude...

I have the correct original vacuum canister from a car I parted out years ago. PM me if interested.

I missed the canister missing part.

Hey guys thanks for the responses! - and the offer, . Maybe I'll have search the interwebs for a pic but I will have to get the diagram/ - vacuum and electrical in the near future.

Technically speaking, this should not happen, as the parking pawl in the column should only be released by vacuum being applied to the vacuum motor on the column, via the vacuum release valve, which is actuated by the courtesy lamp switch and the tilt-away relays. Perhaps there was just enough vacuum produced by the engine immediately after the ignition switch was turned off (tripping the relay and actuating the vacuum release valve) to pull on the vacuum motor. Anyway, I'm thinking that what you describe would be normal, if you had a vacuum reservoir, as the reservoir is designed to store enough vacuum to operate the tilt-away 3 times without engine vacuum.

Is it possible the vacuum line is hooked up to the manifold but there is no canister in the system. This would explain why the system worked right when you shut down the engine since there would still be some vacuum available.

Hey Bart,
Do you have wiring diagram too?

This is normal, and indicates your tilt-away system is in very good condition. There was vacuum in the system when you shut off the engine, so the system did what it was supposed to do. The tank merely insures that it will work if you wait, or the system is worn, etc.
