Recirculation Control Motor Circuit Troubleshooting
WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
- Check the No. 30 (10 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
- YES - Go to step 2.
- NO - Replace the fuse, and recheck.
- Disconnect the recirculation control motor 7P connector.
- Turn the ignition switch ON (II).
- Measure the voltage between the No. 1 terminal of the recirculation control motor 7P connector and body ground.Fig 1: Measuring Voltage Between No. 1 Terminal Of Recirculation Control Motor 7P Connector And Body Ground

Is there battery voltage?
- YES - Go to step 5.
- NO - Repair open in the wire between the No. 30 (10 A) fuse in the driver's under-dash fuse/relay box and the recirculation control motor.
- Turn the ignition switch OFF.
- Test the recirculation control motor (see RECIRCULATION CONTROL MOTOR TEST
).
Is the recirculation control motor OK?
- YES - Go to step 7.
- NO - Replace the recirculation control motor (see RECIRCULATION CONTROL MOTOR TEST ), or repair the recirculation control linkage or doors.
- Disconnect A/C control panel connector A (22P).
- Check for continuity between the No. 5 and No. 6 terminals of A/C control panel connector A (22P) and body ground individually.Fig 2: Checking Continuity Between No. 5 & 6 Terminals Of A/C Control Panel Connector A (22P) And Body Ground

Is there continuity?
- YES - Repair any short to body ground in the wire(s) between the A/C control panel and the recirculation control motor.
- NO - Go to step 9.
- Turn the ignition switch ON (II), and check the same terminals for voltage to body ground.Fig 3: Checking Continuity Between No. 5 & 6 Terminals Of A/C Control Panel Connector A (22P) And Body Ground

Is there any voltage?
- YES - Repair any short to power in the wire(s) between the A/C control panel and the recirculation control motor. This short may also damage the A/C control panel. Repair the short to power before replacing the A/C control panel.
- NO - Go to step 10.
- Turn the ignition switch OFF.
- Check for continuity between the following terminals of A/C control panel connector A (22P) and the recirculation control motor 7P connector.A/C CONTROL PANEL CONNECTOR A (22P) AND RECIRCULATION CONTROL MOTOR 7P CONNECTOR

Is there continuity?
- YES - Check for loose wires or poor connections at A/C control panel connector A (22P) and at the recirculation control motor 7P connector. If the connections are good, substitute a known-good A/C control panel, and recheck. If the symptom/indication goes away, replace the original A/C control panel.
- NO - Repair any open in the wire(s) between the A/C control panel and the recirculation control motor.
