My wife tells me the blower motor in our 96 Bonneville is pretty noisy. I checked it out myself, and sure enough it is. :?

After taking it out of the housing, I find the inside of the housing loaded up with a mice nest, [no mice though] and loads of other crap stuck in the fan blade itself. I got out my shop vac, and I believe I cleaned it all out.

My question is, how are they getting in there? The screens covering the air inlets near the wipers are all in place, and secured properly. So... How are they getting in? :? I don’t want to have to keep cleaning this out again and again.

Thanks for your help.

Mice are tricky bastards. You'd be suprised the tiniest spaces they can get into. You could have left the window down one night and they crawled in through your air vents by the floor, or some small crevace i don't even know about! Just keep an eye on it.

mice in the garage or something
