99 T&C Door look problem

So, the way the door cyclinders are supposed to work, if you turn the key to
unlock and hold for one second it will unlock all the doors. That works
great on the passenger side door of my van.

On the driver side, however, it doesn't. Instead, it will unlock all the
doors for as long as you hold the key turned but as soon as you release
pressure to turn the key back to the nuetral position so you can remove it,
it re-locks them all. This can go on for minutes. Someties I will get it to
stay unlocked after several attempts, sometimes it just won't.

I know if I had the keyless fobs I wouldn't have this problem, but I don't.
;-)

Any thoughts on this? could it just be the computer flaking out so that
resetting the computer might take care of it or is it more likely a faulty
sensor or switch in that lock cylinder itself?

TIA for any help

 

It is not the computer but the arm/disarm switch that is causing the
problem. The switch is attached to the door lock key cylinder. about $30 for
the part.
