Mode Control Motor
Test
Connect batterY power to the No. 4 terminsl of the
mode control motor and connect ground to the No'
8 terminal.
Using a jumper wire, short the No. 8 terminsl in-
dividually to the No. 1, 2, 3. 6 and 7 terminals, in
that order.
a Each time the short circuit is mad€, the mode con-
trol motor should run smoothly and stop.
NOTE: ll the mode control motor does not run when
shorting the tirst terminsl, short that t€rminal again
after shorting the other terminals.
The mode control motor is no.mal it it runs when
shorting the tirst terminal again.
lf the mode control motor does not run in step 2, re'
move it, and check ths mode control linkage 8nd
doors for smooth movement. It the mod€ control
linkage and doors move smoothly, replace th€ mod€
control motor.
Disconnoct ths mode control motot 8P connector,
and remove it from lhe heater unit.
Remove the two sclsws, mode control motot, and
flango coll8,.

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.

There should be continuity b€tween the A and C termi-
nals when Dower and ground are connected to the B and
D terminals.
There should be no continuity when power is discon-
nected.

CAUTION:
. All SRS electrical wiring harnossos are cover€d withyellow insulation.
. B€fors disconnacting any part of the SRS wire har-ness, connsct the 3hort connsctor(s).. Replace the entirs affscted SRS harness assembly itit has an open circuit or damaged wiring.
NOTE; The original radio has a coded theft protection
circuit. Be sure to get the customer's code number
before- disconnecting the battery.- removing the No.32 (7.5 A) fuse from the under-
hood fuse/relay box.- removing the radio.
After service, reconnect Dower to the radio and turn it
on. When the word "CODE" is displayed, enter the cus-
tomer's 5-digit code to restore radio operation.
