Did you change the cabin filter? Look in your owner’s manual for that, it’s usually behind the glove box.

It’s most likely mouse or rodent pee. BillRussell is right about where to start. It might also be mold. This is the time of year that strikes. Here is [an article by John Paul the Car Doctor from our sister publication](http://bestride.com/research/car-doctor/car-doctor-qa-fix-my-stinky-air-conditioner) that may be helpful. This is a great DIY project.

This is how I handled a mice nest on top of the cabin air filter.

> 2013 Chev. Equinox, 20k miles. First thing this morning noticed bad smell in the Equinox with the AC on. Pulled out Cabin air filter at lunch time and it was nearly clogged with hair, some mouse poo and a pile of maggots. Inside the filter housing it looks like a lot of hair. I’m going use a shop vac to clean out as much as I can from the filter opening. I am not sticking my hands in there. I didn’t see any obvious ways in, the cowl screen is properly installed. This has never happened to…
