The spring that makes the key return to "run" after "start" won't return. It just stays in "start" position (and cranks the starter) unless I turn the key to "run" manually. It's on the 1971. Could be coincidence but it began having this problem after it got cold here (like 35 degrees,,,, ok cool for you snow guys;)). Maybe something's binding up or need some kind of lube?? Any ideas appreciated.

Sounds like it mite need took apart and lubed...Dirt and stuff over time getting in there and mixing with the old lube and turning into a little bit of glue..Could be part of the issue or all of it...Or you could get a can of that dry lube i think and spray in there...Grafite or whatever...our local postoffice has to do it alot on our old lock..lol...Im sure some one will be along with the right product or good idea...I never had to by it yet...But i think it needs a dry lube of some kind...That is think ;)

The return spring is inside of the ign switch

Remove the plastic column cover to access the linkage rod

You can pop the rod out so you can move the switch rod and key assy

by hand to see which is tight

ALSO check the lock out rod - have had them cause binding before too, if they are not in the correct spot.

 
Could also be the reverse lockout rod is binding under the stearing column.

Happened to me. Mine did not stick as you descibe but the starter would

randomly engage when I was not touching the key. Assuming you have

that mechanism.

And it's OMS by a nose! but they are both correct!
Brings up another issue. What is the purpose of the rod

and what cars came with it? I have been told it was a

rare option.

Mike the lock out rod came on every 71-3

Although it is called a lock out rod by most guys, it is a safety devise

The main purpose for it is so you can kill the ignition while driving

[ emergency / throttle sticks ] and not lock the steering wheel.

On 3 and 4 speed cars you need to put trans in reverse to remove the key

On auto trans cars , needs to be in park.

 
Thanks guys.

I put a small heater inside the passenger compartment for about an hour to see if it was related to the cold weather.

It works normal, so cold IS making it malfunction. Maybe the spring doesn't work when it's cold??

 
The lube would be in the key cylinder, am I right?

The key works fine when it's cold in all positions, except the spring doesn't return it to "run" after i release it from the "start" position.

How would a guy go about, say, hooking something like that up to something like an AOD swap, for instance? Is it something that could just be blown off, or is it something else I'm going to need to figure out?

(Sorry to steal the thread, 1971Mach1 - I promise I'll bring it right back ;) )

Thread back from the dead. Mine just started doing this as the weather got cold. Did you get this resolved and how? Can I avoid taking apart the column and get some cleaner in there and then graphite "lube" or take the thing apart?

What would be the fun of not being able to take it apart? ::chili::

Sorry, man! I couldn't resist.

It's funny. As I wrote that I knew that I would probably be taking it apart and thus learning more about the ignition system and steering column then I ever thought I would,

And, keeping Don in business when I break something therin and have to order a new part.

The proper place for my lock out rod is in the scrap metal bin!

 
Whatever you do don't spray WD-40 into the lock cylinder. It will cause the grease that is in the cylinder to harden and then you will have a bigger problem. As Don said the issue should be all in the switch mechanism and not the lock cylinder.

I'm thinking that this is exactly what someone did.

Just picked up a 73 yesterday that has the same issue. Key not returning after starting. Did you get this resolved without taking apart the steering column?
