Recirculation Control Motor Test (cont'd)
4-door with M/T, 2-door
NOTE: Before testing, check for HVAC DTCs (see page
21-9).
1. Disconnect the 7P connector from the recirculation
control motor.
Incorrectly applying power and ground to
the recirculation control motor will damage it.
Follow the instructions carefully.
2. Connect battery power to the No. 1 terminal of the
recirculation control motor, and ground the No. 2
terminal; the recirculation control motor should run,
and stop at Fresh. If it doesn't, reverse the
connections; the recirculation control motor should
run, and stop at Recirculate. When the recirculation
control motor stops running, disconnect battery
power immediately.

3. If the recirculation control motor did not run in step
2, remove it, then check the recirculation control
linkage and door for smooth movement.
• If the linkage and door move smoothly, replace
the recirculation control motor (see page 21-57).
• If the linkage or door sticks or binds, repair them
as needed.
• If the recirculation control motor runs smoothly,
go to step 4.

4. Measure the resistance between the No. 5 and
No. 7 terminals of the recirculation control motor. It
should be between 4.2 and 7.8 k .
5. Reconnect the recirculation control motor 7P
connector, then turn the ignition switch to ON (II).
6. Using the backprobe set, measure the voltage
between the No. 3 and No. 7 terminals.
Fresh: About 1.0 V
Recirculate: About 4.0 V
7. If either the resistance or voltage readings are not
as specified, replace the recirculation control motor
(see page 21-57).
