We have just started having a problem with our 03 Tundra. Twice in 3 weeks we've had mice get into the dash... not the engine, but actually in the fan in the heater/ac duct. Turn on the ac, hear a thump, take out the fan and out falls a dead mouse. Turn on the ac, hear noises, take out the fan and pull out a mouse nest. Where are these mice getting into the dash?? We are thinking under the cowl louver? Can't think of anywhere else. Anyone else familiar with this?

I had a mouse problem on my 95 t100, It seemed like every other day i would hear that dreaded "thump" then the blower would vibrate. I would have to pull the blower and get the mouse out. I finally found a nest in the rear storage compartment and removed it (complete with baby mice) it stopped them for a while. but it would happen every once in a while after that. I hope they don't find a way into my 05 Tundra, It was a very aggravating experience.

I was looking into a mouse repellent, basically it was fox urine in powder form, its a mouse's natural predator, so its supposed to keep them away. Never use Decon, they will just die in the vehicle somewhere you cannot reach them, and it will stink for a couple weeks!

Dead Mouse in 2005 Camry

my 2005 camry has a dead mouse in the blower as well. How do you access the blower to get the dead mouse out? Many Thanks for the Help!

Wish I could help....An adult mouse can go thru a dime size hole, my 89 had air filter housing so full of insulation, grass, leaves, twigs, my truck wouldn't run, Darrin

Pretty sure they're getting in through the cowl vent. The black plastic grille on my 2006 tundra looks like it would keep rodents out, but they can get in around the windshield wipers, and also under the ends of the cowl grille. Rather than try to plug those holes effectively, I removed it and attached hardware cloth over the gigantic holes underneath.





There is a hole (drain?) right in the middle, so I covered that as well since it's probably big enough for a mouse to get through.



Hope this does the job. I'm tired of pulling out the heater blower to remove mouse nests.

Hey, did this work for you? Have the mice come back at all? I'm having the same issue. Unfortunately, the pics you attached aren't working.

Maybe I should ask in camry forum, but this old thread caught my attention. So....Visiting friend out of state at the time. Camry 2012 or 13? Location...rural country. Asked about bad smell inside car & was told been there for awhile. I ended up pulling the caf out..stuck my hand down inside...dead mouse jammed in fan blades.

I cleaned out & replaced filter. I did look around, but couldn't figure out (at that time) how mouse got in? If it happens again, then more investigation needed. Anyhow, tks. for info.

Sorry, I just saw this because I'm back here again looking for the same answer. No, hardware cloth over the cowl vents did not work, and I'm still pulling Toyota insulation out of the heater. For one thing, I don't know where the dang mouse is getting so much insulation! I guess it's carpet padding, but I don't notice any low spots in the rug. I actually had to cut an inch-and-a-quarter hole in the front of the heater box to get nesting (and once a dead mouse) out of there. I've taken the blower out so many times that I've had to start using larger screws.

I installed a battery-powered rodent repeller stuck to the underside of the heater box, but today I pulled out a couple handfuls of insulation. The one thing that does seem to help is squirting peppermint oil in the heater. I covered that hole I cut in the plastic housing with an electrical box plug - a little metal cap thing that snaps in the hole. I remove that, pull out the crap with long tweezers and the shop vac, then squirt peppermint oil inside the box. I also put oil in the blower cage before reinstalling that. Seems to work for a while, but I have to remember to refresh the oil once the truck stops smelling like a candy store, or the critters come back.
