I have a 2000 Honda Accord 4 door , I think that somewhere in the car I
have a dead mouse.
The worst smell is when you first get in it after it had been closed up
in the garage all night.
If you run the blower motor with heat or AC the smell does not seem to
be coming from
the vents so I think the smell is coming from inside of the car but I
can't seem to find it.I have looked under the seats
and under the dash with a mirror. I don't know how to remove the back
seat so I have not
looked under it.
A couple of years ago I had a mouse nest inside of the heater fan so now
when I park it in the
garage we make sure that the recycle air button is lit so it blocks the
outside vent.

I thought maybe someone else has had the same problem and could suggest
where I should look.

Thanks
