HI all

For several months I hear a constant noise from below the car flooring, and need help to know if I can easily fix it. I believe my kid might have dropped something metallic (probably a small AA battery inside the air-conditioned openings below the driver seat and that "thing" is just banging around there.
When I accelerate or brake, it hits somewhere and makes noise. For me, the sound seems that comes from the back of the car, for someone on the rear seat it seems that it comes from the front.

Anyway, I would like to know if there is a (easy) way for me to fetch whatever dropped inside that hole on the floor.
This is a company car, so I can be messing around or break stuff, and taking it to the official company mechanic may be expensive..
Maybe a magnet will do the trick?

Thanks

 

Luckily I found the noise source... it was a small kid's car inside the rear door armrest
