My 98 Jimmy has an intermittant problem - the ignition cylinder will
not rotate from RUN to the OFF position.
I confirmed that the key cylinder solenoid works fine, and that the
Transmission Controller (under the shifter) properly closes the circuit
(pins C and F) when in the park position. Usually the solenoid
properly pulls in when in Park, sometimes it does not.
I can't reproduce the problem right now - has anyone seen this problem
