I turned on the heat after my volvo 850 was sitting in the garage for about a year and mouse crap flew out of the vents, how can i fix this?

 

First find the source then kill it. Then dont eat the donut...those aren't chocolate sprinkles.

 

I heard cheese is good

 

You need to find the mouse and take it out first and foremost. Put a mouse trap in the car with some peanut butter and get that thing. Once you know all the mice are gone, you will need to clean out your HVAC system. Not fun.
