2. Connect battery power to terminal No. 6 of the passenger's air mix control motor, and ground  
terminal No. 7; the passenger's air mix control motor should run smoothly, and stop at MAX HOT.  
If it does not, reverse the connections; the passenger's air mix control motor should run smoothly,  
and stop at MAX COOL. When the passenger's air mix control motor stops running, disconnect  
battery power immediately.  
3. If the passenger's air mix control motor did not run in step 2, remove it, then check the passenger's  
air mix control linkage and door for smooth movement.  

If the linkage and door move smoothly, go to step 4.  

If the linkage or door sticks or binds, repair them as needed.  
4. Measure the resistance between terminals No. 1 and No. 3. It should be between 4.2 kohms and 7.8  
kohms.  
5. Reconnect the passenger's air mix control motor connector.  
6. Turn the ignition switch to ON (II).  
7. Using the backprobe set, measure the voltage between terminals No. 2 and No. 3.  
MAX COOL: About 1.0 V  
MAX HOT: About 4.0 V  
8. If either the resistance or the voltage readings are not as specified, replace the passenger's air mix  
control motor.
