    Will a bad fan control module cause the check engine light to come on

    Min is having this problem what should I do

    Fans work, mouse homeless, cold and confused.

    Just like Lunch Bucket Joe. “These socks don’t match, or do they!”

    Hey I had the same problem with my 2005 Mazda 6 v6, I swapped out the fan control module and it basically did nothing for me. Any tips on what else it could be? Thank you

  5. Avataaar/Circle Created with python_avatars Jimmy D says:

    Great video for reference. My fan control module just went bad a few weeks ago on my 2004 Mazda 6s.

    I have a 2010 mazda 6 2.5L both fans isn't working brand new assembly. I had the other brand new assembly returned because the cooling fan would stay on. Like wtf

    You should be wearing a dust mask when messing abound that mouse stuff!(PPE rant)

  8. Avataaar/Circle Created with python_avatars Anā Yasser says:

    Do you still need some like computer stuff to perform some updates or to erase some codes before replacing the CFM? or just directly replace the module itself?

  9. Avataaar/Circle Created with python_avatars Walter White says:

    I have a 2006 Mazda 6 ,my fan runs all the time from the time it's cranks and only turns after shutting off the engine, do you think this could possibly fix my problem also?

  10. Avataaar/Circle Created with python_avatars The Crazy life of Kim says:

    I have a 2010 mazda 6 v6 and i can’t find the FCM, please help,….

  11. Avataaar/Circle Created with python_avatars Martín H. says:

    QQ, how do you know that the Fan will turn on w/o the AC on? I had just replaced my 2004 Mazda 6S FCM and I see both fans only working when I turn AC ON. Thank in advance for your support. amazing videos!!!

    Anyone measure the fan motor resistance? Want to make sure motor isn't shorting out.. mine is at 0.4ohms

  13. Avataaar/Circle Created with python_avatars zx3zetech ford says:

    You should have just left the rate nest, it was helping keep the car quiet seeings how that's just a resonance chamber that you pulled it from and air doesn't actually get pulled though that location which makes it even funnier when your like oh this cars going to breath better now! Lol. Great videos though, keep up the good work!

  14. Avataaar/Circle Created with python_avatars Mike Chiodetti says:

    "That'sa nicea fix. You gooda man!" My best impression of an Italian woman who'sa nowa happy!
    Like my impression? Did you notice the way I "enunciated" the words? Cool huh?! LOL!
    GREAT VIDEO! You should have wired that old module to DC fan. Talk about "high output!" Woulda been a great shop fan!

  15. Avataaar/Circle Created with python_avatars Cathy Kelley says:

    Hi! Thank you so much for this video. We replaced the module and it took care of the issue of the running out of control fans. But, now there's a slight smell, like burning coolant? Been a few months, Coolant level hasn't changed. What do I need to look for?

  16. Avataaar/Circle Created with python_avatars dave scott says:

    i can tell they washed it

  17. Avataaar/Circle Created with python_avatars MB 320 says:

    Thanks!

    Thanks for the video.

  20. Avataaar/Circle Created with python_avatars WildWhiteFang says:

    Ironically I find this video after I diagnosed and replaced mine a week ago on my 2008 Mazda 6 V6. If anyone wants to replace thiers make sure youu get the part from Mazda. They even knew about this and made updated parts

  21. Avataaar/Circle Created with python_avatars Angel F says:

    Will this cause the car to over heat if the fan control module is bad

  22. Avataaar/Circle Created with python_avatars URGENT! "Cory Barbee" YT ch.👀 says:

    they put it behind the radiator so it can get hot lol but i guess its only getting hot air half the time until the thermostat opens up again and puts more hot coolant in the radiator.

  23. Avataaar/Circle Created with python_avatars tom b says:

    I have an 03 Mazda6 the fans would not kick on I have now replaced the module and both fans and as soon as you start the car they go into high and stay on high mode I've also tried to warranty the module with no change

  24. Avataaar/Circle Created with python_avatars tom b says:

    okay here's one for you I have an 04 Mazda 6 we've replaced the both fans and the control module before the fans wouldn't kick on and it would overheat now the fan stays on high without the AC on and with AC on kicks on and off of High another note is my scanner shows zero fan signal any help would be appreciated

    1 down voter was the mouse who's home was removed from the air intake.

  26. Avataaar/Circle Created with python_avatars Michael Afruma says:

    This was the first video of yours that I have watched. It was the exact problem that I was having on my 05. Your step by step walk through is excellent. 10-15 min, including just poking around a bit, with a 10mm ratcheting wrench and a flat head screwdriver and I was done. I got better performance from the the car immediately. Thank you for the knowledge transfer!

  27. Avataaar/Circle Created with python_avatars Nickey Black says:

    Great job. My Mazda does the same thing. I'm curious though. How much did you charge her for the repair, and how much would've Mazda charged for the repair?

  28. Avataaar/Circle Created with python_avatars Mr. Nobody says:

    Pretty easy fixed, A + Eric O.

  29. Avataaar/Circle Created with python_avatars Channel8753 says:

    thank you brother for the video

  30. Avataaar/Circle Created with python_avatars Mz. Q. Blessed says:

    after installing should the car overheat?

  31. Avataaar/Circle Created with python_avatars beerdrinking504 says:

    Good video dude. saved me a bunch of money which is always nice.

  32. Avataaar/Circle Created with python_avatars flay me-yong says:

    where can i buy the original part
    link or website

  33. Avataaar/Circle Created with python_avatars Matt Nemeth says:

    Any thoughts on if you replace FCM and still have fan issues?

  34. Avataaar/Circle Created with python_avatars Yamaha R1 says:

    I have a Mazda 6 2006 with 142,000 km.  Started doing the same thing a few days ago.  Thank you very much for the video, it was awesome!  I should be able to  do this myself after watching it.  Thanks again and definitely thumbs up!

  35. Avataaar/Circle Created with python_avatars Domenic Boscariol says:

    Very helpful video … always nervous about trying repairs but the video going through the whole process was ideal. thanks again!

  36. Avataaar/Circle Created with python_avatars John McKamy says:

    I love the Djoint pliers

  37. Avataaar/Circle Created with python_avatars Louis B.B says:

    would the process be the same for a Mazda tribute? I've had a look and the module appears to be the same

  38. Avataaar/Circle Created with python_avatars Brandon Harlow says:

    My '05 Mazda 6 V6 just started doing the same thing yesterday. 176,000 miles and I am the only owner. There was actually a recall for this module for cars between 2003-2005. Apparently Mazda replaced mine during a service in 2009 so they won't replace it again for free. Got the part off RockAuto for $60 and will replace it myself-The dealer quoted $150 part and $100 labor hahaha. Shouldn't be hard with my aftermarket intake. I have all sorts of room in that area. Thanks so much for the video. Sub'd!

  41. Avataaar/Circle Created with python_avatars John McIntire says:

    This video helped a lot, paid 31.00 for part on eBay and installed in 15 minutes. Thanks

  42. Avataaar/Circle Created with python_avatars Keema Chiles says:

    I have the same car same year as well and the same problem. Is the new Mazda peice the only problem it could be and what's a good price for one?
