Mode Control Motor Test

2006 Chevrolet Cobalt SS, 4D Sedan, StandardSECTION Mode Control Motor Test
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before testing, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATIONΒ  ).
  1. Open the glove box. While holding the glove box, release the glove box stops on each side from the dashboard by pushing them in, then lower the glove box (see step 1 ).
  2. Disconnect the 7P connector from the mode control motor.
    NOTE: Incorrectly applying power and ground to the mode control motor will damage it. Follow the instructions carefully.
  3. Connect battery power to terminal No. 1 of the mode control motor, and ground terminal No. 2; the mode control motor should run smoothly, and stop at Vent. If it doesn't, 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.

  4. If the mode control motor did not run in step 3, 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 (see MODE CONTROL MOTOR REPLACEMENTΒ  ).
    • If the linkage or doors stick or bind, repair them as needed.
    • If the mode control motor runs smoothly, go to step 5.
  5. Use a digital multimeter with an output of 1 mA or less at the 20 kΞ© range. With the mode control motor running as in step 3, check for continuity between terminals No. 3, No. 4, No. 5, and No. 6 and terminal No. 7 individually. There should be continuity for a moment at each terminal as the motor moves past the switch's terminal.
  6. If there is no continuity for a moment at each terminal, replace the mode control motor (see MODE CONTROL MOTOR REPLACEMENTΒ  ).
