Ever since I have had a car equipped with A/C I have made it a habit of turning off the A/C compressor a distance from my final for the day destination and letting the cabin vent fan run to dry the moisture from the evaporator and other surfaces that under some conditions can develop some condensation. Do not know where I picked this up but it has served me well all these years.I do what A Guy suggested. When I'm about a minute from my destination, I turn the AC off and let the vent air in. My 2009 didn't have a cabin filter, but it appears your 2010 does. Maybe this is a problem if your's has never been changed?
I had a similar problem with a 2005 Grand Cherokee. It ended up being caused by mice nesting in the heater core. It also resulted in heater core failure due to the corrosive effects of the mouse urine.Anyone else have any problems with an urine/ammonia smell sometimes in the cabin of their car? It comes and goes but man is it annoying. 2010 Fuchsia Dodge Challenger R/T
Hope not hope it is just a past its change by date cabin air filter but I'm suspect you and others are right. The "urine/ammonia" smell is probably due to rodent (mouse most likely) urine in the heater/AC system.I had a similar problem with a 2005 Grand Cherokee.
