Passenger's Air Mix Control Motor Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.

Special Tools Required

Backprobe Set 07SAZ-001000A (2)

NOTE: Before testing the sensor, check for climate control DTCs (see GENERAL TROUBLESHOOTING INFORMATION ).

Disconnect the 7P connector from the passenger's air mix control motor.
NOTE: Incorrectly applying power and ground to the passenger's air mix control motor will damage it. Follow the instructions carefully.
Connect battery power to terminal No. 1 of the passenger's air mix control motor, and ground terminal No. 2; the passenger's air mix control motor should run, and stop at Max Cool. If it doesn't, reverse the connections; the passenger's air mix control motor should run, and stop at Max Hot. When the passenger's air mix control motor stops running, disconnect battery power immediately.

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, replace the passenger's air mix control motor (see PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT ).
- If the linkage or door sticks or binds, repair them as needed.
- If the passenger's air mix control motor runs smoothly, Go to step 4.
Measure the resistance between terminals No. 5 and No. 7 of the passenger's air mix control motor. It should be between 4.2 and 7.8 kΩ.
Reconnect the passenger's air mix control motor 7P connector, then turn the ignition switch to ON (II).
Using the backprobe set, measure the voltage between terminals No. 3 and No. 5.
Max Cool: About 1.5 V

Max Hot: About 4.5 V
If either the resistance or the voltage readings are not as specified, replace the passenger's air mix control motor (see PASSENGER'S AIR MIX CONTROL MOTOR REPLACEMENT ).
