From the FSM:

AG AND AJ BODIES

After completion of a turn the system is deactivated
automatically. The cancellation switch in the steering
column sends a signal to a remote turn signal switch
in the switch pod to cancel the turn signal function.
As the steering wheel returns to the straight ahead
position from a turn, a cancel cam which is located on
the steering wheel contacts a cancel flipper located on
the cancellation switch. When the flipper is contacted
by the cancel cam in the proper rotational direction,
the cancel switch sends a signal to the remote turn
signal switch.


DUAL-FUNCTION SWITCH TESTS—AG AND AJ
BODIES

To test the cancellation portion of the switch:
(1) Reconnect battery and switch connector (Fig. 5).
(2) Connect voltmeter positive lead (+) to pin 8 and
negative lead (-) to ground.
(3) Place ignition switch to the ON position. Voltmeter
should read battery voltage. If no voltage is
present, check feed wire to pin 8. If battery voltage is
present continue with switch test.
RIGHT CANCELLATION TEST
(1) Connect one side of a jumper wire to pin 3 and
the other end of jumper wire to ground.
(2) Connect the positive lead (+) of a voltmeter to
pin 5 and the negative lead (-) to ground.
CAUTION: Do not allow pin 5 to become grounded
during test, switch failure will result.
(3) With the ignition switch in the ON position,
push the cancellation pawl down and read the voltmeter.
(4) The voltmeter should show at least 9 volts.
(5) If voltage is 0 to 8 volts the cancellation switch
is defective. If voltage is 9 volts or more the cancellation
switch is working correctly.
LEFT CANCELLATION TEST
(1) Connect one side of a jumper wire to pin 4 and
the other end of jumper wire to ground.
(2) Connect the positive lead (+) of a voltmeter to
pin 5 and the negative lead (-) to ground.
CAUTION: Do not allow pin 5 to become grounded
during test, switch failure will result.
(3) With the ignition switch in the ON position,
push the cancellation pawl up and read the voltmeter.
(4) The voltmeter should show at least 9 volts.
(5) If voltage is 0 to 8 volts the cancellation switch
is defective. If voltage is 9 volts or more the cancellation
switch is working correctly.

REMOTE TURN SIGNAL SWITCH TEST—AG
AND AJ BODIES
The remote turn signal switch is located on the left
side of the instrument panel switch pod. To test,
remove switch pod assembly from instrument panel.
Using an ohmmeter, test for continuity between the
terminals of the switch as shown in the following
continuity chart (Fig. 6). The white 7 way connector
next to the 14 way connector must be connected when
performing continuity checks.

CANCELLATION SOLENOID TEST—AG AND AJ
BODIES
To test the turn signal cancellation solenoid:
(1) Remove switch pod from instrument panel.
(2) Connect one end of a jumper wire to the positive
terminal of the battery, the other end to pin 6 of the
turn signal switch 14 way connector.
(3) Place turn signal switch in the left turn mode.
(4) Take a second jumper wire and connect one end
to a good ground. Momentarily touch the other end of
the jumper wire to pin 11 or 14. The solenoid should
energize, and return the switch to its center OFF
position.
(5) Place turn signal switch in the right turn mode.
(6) Repeat step 4. The solenoid should energize,
and return the switch to its center OFF position.
(7) If switch does not return to center in either
direction, the switch is defective.

So in short there is a cancelling switch (the one with the flipper) that tells the cancelling solenoid to turn off the turn signals. It is my understanding that the cancelling switch is the part that fails.
