Self test of climate control system 2011 Honda CR-V. Self test for HVAC AC Blower Hot Cold Blend. Blend Door was not working properly when I took this video. All functions of the climate control are tested. In my case the AC worked but no heat was working. All AC HVAC functions are tested as well as recirculation

Straight to the point! I appreciate the information shared here. My AC still blows hot air. I tried the diagnostics sequence, it worked but I got no flashes at all. The system was telling me all is well lol

Thanks for the info and link. A/C was blowing through defrost. The diagnosic process gave open or short in mode control circuit. I did it the second time and it's working properly. Of I hadn't seen this I would have been testing the blend door motor then tested the circuit. I appreciate the information. Thanks again!

I watch several videos and this is by far the most helpful one.

Followed the instructions for my 09 CRV. Got two blinks. Thank you.

I just bought a 2009 CRV, and tried to use the A/C, it was blowing hot air on a hot day. I tried your procedure and started blowing cold air, no flashing lights. its been working fine for two days. I wonder why wasn't it working before? Great video

[k.g.]

Worked to fix my cold-air-only situation, but read my steps:
Previously I had proper heat and AC, but my vents would not change where they would blow. It would blow to the floor no matter which button I picked, including defrost. To fix it I used to whap the device with the green plug with a hammer. That would restore service for about a year.
But NOW I have an issue of no heat - I was just getting cold air. I was skeptical that this video was addressing vent direction and not air temperature, but I was wrong. The trick does work, but unlike the video, unplugging and replugging with the car OFF did not work for me. So I tried it a second time with the car running, with the blower on high, and the heat to max and it DID WORK INSTANTLY! The cold air turned hot right away. Keep in mind I did this repair after driving around a bit so my engine was warm and able to provide engine heat to the heater unit so I could tell if any of my attempts to fix were successful.
Thank you Danny Jensen!

This just reset my a/c that was blowing hot air on one side. Thanks!

Thank you for providing this troubleshooting test and the link to the Service Manual: all very helpful!

[nileshpakhare]

Thanks. It worked for my 07CRV. Ac is back on and working fine.

If you have a model with climate control the self test can be enabled by turning the key to II then hold off/on and press rear defrost 5 times.

Thank you so much. This info helped me save so much time.

6 blinks, replaced blower resistor and checked all fuses and relays in document. Still no air, ideas?

[debbiepoots]

Where in the manual do you find the corresponding codes? Mine is flashing 4 times

[livingstongonzalez]

Thanks a lot, i have my air condition again.

[JT-uisn]

Great video, thanks. I’m getting 10 blinks, but can’t find what this means. Any ideas? TIA

[jacklynelmer]

Can i get the link for the service manual, please!

[fiyzcfd]

Did this test and no blinking light. However my CRV still blows full hot. Ideas?

[jacklynelmer]

Since its blowing just cold air do i do test on heat side of climate control?

[davidroberts]

AC stopped working this summer and now we have no heat. I performed this test and had no errors. The test played out just the same as your video. Can you suggest a next step?

Thanks for your informative videos.

No blinks when I ran the test on my 2010. Tapped the actuator motor a bunch and unplugged/replugged green clip. Actuator moves and is functioning when I move from hot to cold air and back again. My radiator was replaced a week ago because of a leak but that didn’t solve the problem. Still getting only cold air from passenger vents even though driver’s side blows warm. Any ideas?
