Re: Heater/AC Fan Removal?

I have found no surefire way of keeping rodents out. Sometimes mothballs or pepermint oil work, but you probably don't want either near your fan. Using the vehicle frequently will discourage them. If you're parking in a garage, setting traps near the car will help too.

I planned to take my car to the dealer under warranty when I heard the noisy fan, but they were nice enough to tell me that if it turned out to ba an animal, it wouldn't bec overed by the warranty. I can't blame them for not covering it, but they really should have warned you in advance.

Hello.. I also had a problem of mouse getting in..
First you have to stop acceess to the place just under the windshield.
I think they get in there through the water outlet. Then it can go into the hole whare the fresh air get inside. You may cover those 2 holes by using a metel net which have drills that do not allow the troble makers to go in.

To see inside clearly you have to remove the plastic grill. It is not a difficult job.

Remove the caps of the wipers at the root by just pulling it out

And remove the wipers by loosoning the nuts. You may need to fold the wipers out side to remove them easily.

open the bonet. There are 4 clips and 2 plastic bolts. Remove them carefully.
Then you can remove the enitere plastic grill. But it has tubes connected with wires going to the mortor. So you may keep it little away and see inside.

Now you know how to get in there rather than through doors or windows.. :)

I appreciate all of you who have posted, especially the pictures. I had a vibration in my 2011 Leaf fan for a couple weeks, then it stopped completely. Had a mouse nest in there that almost completely filled the fan. But from start to finish, cleaning out the fan only took about a half hour. That electronic unit that some of you had to move wasn't in the way for me. Once I had the glove box out, the fan was just a twist and pull... Didn't even unhook the wire.

I found that spraying diluted Pinesol around the air intake helps. But you need to spray it every few days. Also, a piece of Irish soap would do, It smells bad, but if you get it so it "fragrance" doesn't get inside, you are OK. In general, pieces of steel wool here and there would deter the rodents.

I just removed the blower motor and cleaned the housing. In my case, there were no rodent artifacts, but small pointy leafs from trees here in San Diego. Leaf produced 07/2011. Didn't have to remove computer, it was against the front firewall. Had to pull the harness that was in a way and had a popup pin to one of the frames that is impossible to squeeze and pull out as something is in a way.
The key thing is that press tab on the motor, without someone prior to me in this post pointing to it I would get stuck there.
Other key point is to remove all tools, including small hanging or magnetic flashlight before putting glove box back in. Or you will do all kind of acrobatic moves with your hand laying on your back/shoulders ;-)
And, as you are already there, replace cabin filter-get one ahead of time. :P
Thanks everybody who contributed to this post and instructions !!!!!

Thank you, everyone, for the easy-to-follow instructions and photos. I had a bird feather that was causing noise in my blower fan. I have no idea how something so relatively big got inside. (It was about 5 inches/13 cm long.)
