POTENTIOMETER CHECK While checking the air mix damper control motor, measure the resistances between
terminals numbers 3 and 5 and between numbers 3 and 7. At this time, the
resistances should change gradually within the standard value.
Standard value: 1.7 (MAX HOT) - 5.0 (MAX COOL) kohm MODE SELECTION DAMPER CONTROL MOTOR CHECK Check the mode selection dam

Q: Is the rear blower relay in good condition?
YES:
Go to Step 5.
NO:
Replace the rear blower relay. The rear blower motor should operate
normally.
STEP 5. Measure the voltage at rear blower relay connector C-209.
1. Disconnect rear blower relay connector C-209, and measure the voltage at
the junction block side.
2. Turn the ignition switch to the "ON" position.
3. Turn the blower speed selection dial to the "MAX" position.
4. Turn the mode selection dial to the "Face" position.
5. Turn the rear blower switch to the "ON" position.
