Mode Control Motor
Replacement
1. Disconnect the 7P connector from the mode control
motor. Remove the rod from the arm of the mode
control motor, Remove the self-tapping screws and
the mode control motor.
2.Install in the reveGe order of removal. After installa-
tion, make sure the mode control motor runssmoothlv.
7P CONNECTOR
MODE CONTROL MOTOR
Test
1.Disconnect the 7P connector from the mode control
motor.
Connect battery power to the No. 1 terminal, andground the No. 7 terminal. To avoid damaging the
mode control motor, do not reverse power andgrouno.
MODE CONTROL MOTOR
Using a jumper wire. connect the No. 7 terminalindividually to the No, 2,3, 4,5 and 6 terminals in
that order. Each time the connection is made. the
mode control motor should run smoothly and stop.
lf the mode control motor does not run when jump-
ing the first terminal, jump that terminal again afterjumping the other terminals. The mode control
motor is OK it it runs when jumping the first termi-
nal again.
lf the mode control motor does not run in step 3,remove it, then check the mode control linkage and
doors for smooth movement. lf they move smoothly,
reDlace the mode control motor.

tion control motor should run smoothly. To avoid
damaging the recirculation control motor. do not
reverse power and ground.
RECIRCULANON CONTROL MOTOR
Disconnect the No. 2 or No. 4 terminals from ground;
the recirculation control motor should stop at Fresh
or Recirculate. Don't cvcle the recirculation control
motor for a long time.
lf the recirculation control motor does not run in step
2, remove it, then check the recirculation control link-
age and door for smooth movement. lf they move
smoothly, replace the recirculation control motor.
