    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? (lol2)

    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.
