4. Install the recirculation control motor in the reverse
order of removal. Then apply battery voltage, and
watch the door movement.
• Make sure that the recirculation door moves
smoothly without binding.
• Make sure the motor doesn’t pull the door too
far.
Test
Connect battery power to the No. 1 terminal of the
recirculation control motor, then connect ground to
the No. 2 terminal; the recirculation control motor
should run, and stop at REC.
If it doesn’t, reverse the connections; the recircula-
tion control motor should run, and stop at FRE.
NOTE: If the recirculation control motor does not
run, remove it, and check the recirculation control
linkage and door for smooth movement. If the recir-
culation control linkage and door move smoothly,
replace the recirculation control motor.
2. Check for continuity between the terminals of the
recirculation control motor according to the table.
