Mode Control Motor Test Acura RL II

Mode Control Motor Test

Note. Before testing, check for HVAC DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Scheme 108

1. Disconnect the 5P connector from the mode control motor. NOTE: Incorrectly applying power and ground to the mode control motor will damage it. Follow the instructions carefully.
2. Connect battery power to the No. 1 terminal of the mode control motor, and ground the No. 2 terminal; 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.
3. If the mode control motor did 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 (see «MODE CONTROL MOTOR REPLACEMENT»(/acura/rl/ii-2004-2008/remont/automatic-hvac-system/#hvac) ). If the linkage or doors stick or bind, repair them as needed.
