1. Disconnect the 7P connector from the mode control motor.
2. Connect battery power to the No. 1 terminal and ground the No. 2 terminal; the mode control motor should run smoothly and stop at Vent. If it does not, reverse the connections; the mode control motor should run smoothly and stop at Defrost. When the mode control motor stops running, disconnect battery power immediately.

3. Use a digital multimeter with an output of 1 mA or less at the 20 k ohm; range. With the mode control motor running as in step 2, check for continuity between the No. 3, 4, 5, 6 terminals and the No. 7 terminal individually. There should be continuity for a moment at each terminal.
4. If the mode control motor does not run in step 2 remove it, then check the mode control linkage and doors for smooth movement.

- If the linkage and doors move smoothly, replace the mode control motor.
- If the linkage or doors stick or bind, repair them as needed.
