Recirculation Control Motor
Test
Connect baftery power to the No. 1 terminal of therecirculation control motor, and connect ground tothe No. 2 and No. 4 terminals; the recirculation con-trol motor should run smoothly.
Disconnect the ground from the No. 2 or No. 4 ter-minals; the recirculation control motor should stooat FRESH or RECTRCULATE.
CAUTION: N6v€r conn€ct the batt6ry in ths oppo-aite direction.
NOTE: Don't cycle the recirculation control motorfor a long time.
It the recirculation conttol motot does not run in steD'1, remove it, and check the recirculation control link-age and door for smooth movement. lf the recircu-lation control linkage and doo. move smoothly,replace the recirculation control motor.
Replacement
Disconnect the 4P connector from the recirculationcontrol motor, and remove the wire harness clio fromit.
Remove the two screws, recirculation cont.ol mo,tor and flange collar.

8. Install in the reverse order of removal. and:
it you're installing a new evaporator, add refrig-
erant oil (ND-OIL 8: P/N 38899 - PR7 - A01) (see
page 22-2'll.
replace the O-rings with new ones at each fitting.
and apply a thin coat of refrigerant oil (ND-OlL 8:
P/N 38899 - PR7 - A01l before installing them.
NOTE: Be sure to use the right o-rings for HFC-
134a {R-134a} to avoid leakage.
apply sealant to the grommets.
make sure that there is no air leakage.
charge the system (see page 22-39) and test its
