NOTICE
Incorrectly applying power and g r o u n d to
the mode control motor will damage it.
Follow the instructions carefully.
Connect battery power to the No. 1 terminal of the
m o d e control motor, and g r o u n d the No. 2
t e r m i n a l ; the mode control motor should run
s m o o t h l y , and stop at Defrost. If it doesn't, reverse
the connections; the mode control m o t o r should
run s m o o t h l y , and stop at Vent. W h e n the mode

3. If the m o d e control motor did not run in step 2,
remove it, then check the m o d e control linkage and
doors for s m o o t h m o v e m e n t .
• If the linkage and doors m o v e smoothly, replace
the m o d e control motor (see page 21-84).
• If the linkage or doors stick or bind, repair t h e m
as needed.
• If the mode control m o t o r runs s m o o t h l y , go to
step 4.
4. Use a digital multimeter w i t h an output of 1 m A or
less at the 20 kQ range. W i t h the m o d e control
m o t o r running as in step 2, check for continuity
between the No. 3, 4, 5, and 6 terminals and the
No. 7 terminal individually. There should be
continuity for a m o m e n t at each terminal as the
m o t o r moves past the switch's t e r m i n a l .
5. If there is no continuity for a m o m e n t at each
t e r m i n a l , replace the mode control motor (see page
21-84).
