    HOW-TO: Clean the HVAC blower wheel (mouse cage)

    I had some issue yesterday with the blower vibrating badly. The culprit seems to have been a small rodent nesting in the blower housing. Sorry I didn't take pictures of removing the cowl, I was just curious if I could do anything to it without ripping out the dash. The answer - YES you can! The cowl comes off by removing the wipers, 4 plastic screws/plugs and 4 (I think) push plugs that hold the weatherstripping to the car (passenger side only) Here's some pictures of what I did...

    What I couldn't fish out with a coat hanger bent with a hook on the end, I did the following with a short section of spare waterhose...

    Haha. It wasn't home. I'm thinking that it made a run for it once it's nest started getting sucked away, piece by piece. If this happens again, I'll be installing some screening over the grid opening. I started to, but I was running out of daylight and I still had to wash the thing.

    thanks for the tip, wife's 5 is making a noise when the fan is turned up past 3/4, so maybe we have uninvited guests as well.

    probably wouldn't be a bad idea to install some screen over it to keep the little buggers out

    Thanks for the tip flcruising. I'm surprised there is SO much debris in there! Isn't there a simple sponge filter on top to block stuff like that?

    I don't recall a sponge filter, just the grid you see from above.

    There are drain holes over the struts that I assume are simply for water, but they are definitely large enough for a rodent to enter. Therefore, this wasn't debris collecting over time from washing down through the cowl, something carried this stuff in there.

    Edit: actually you can see the hole on the left side of this picture, and I don't think this was the only one. I suspect a mouse.

    Wow, I am so glad I found this post, thanks flcruising for putting this up. I had the exact same problem, out of the blue major vibration started with low fan speed, I thought the fan bearings were suddenly shot or something. I was just about to take the 5 into Mazda where I'm sure they would have charged me hundreds to figure it out.

    Here is dead mouse:


    Removed with garden hose vacuum attachment


    There was a nest in there too, so I decided to improve on Mazda's design. I took an old plant pot tray and after
    measuring the dimensions of the air inlet, cut it to size.


    Then I trimmed to fit and wedged it solidly over the existing opening. It fit perfect and very tight, the holes
    are smaller than my finger, just over 1/4", so no more mice will be getting in there again.

    Excellent addition Mickee13. Thanks!

    You've confirmed my suspicions as well as given a good solution.

    Brown's Fairfax Mazda charged me $100 to clear the housing. Mice and other small critters love that space, unfortunately.

    Wow!. So if you have vibrations, you're breathing mouse parts?

    Good to know about this. Thanks

    I had a mouse a few months back though mine apparently went through the cabin filter (hole chewed through it), then it built a nest in the blower motor. What happened was that when I would turn on the blower no air would come out.

    So I took it to the dealer thinking it would be covered by warranty - they claimed it took 3.5 hours of labor to take the blower motor out to clean it, then put it back. $350, and not covered by the warranty, because of mice. Next time obviously I'll do it myself, the only reason I took it there was because I thought it would be covered. At least I got a chance to rip them on the post-service phone interview - hopefully it was Mazda corporate and not the local dealer's person calling.

    I have never heard of a vehicle having mouse issues before the Mazda5.
