Car stink


#1

An overnight putrid/foul odor appeared in a 2002 Civic. Can’t find a single culprit. Any ideas on what it could be and what to do about it?


#2

Saturated charcoal canister
skunk
rotting leaf or other debris in vents (below windshield)
Dead mouse in heater duct (these miserable #%$^&@ can crawl through a hole 1/4 their size!)
Perhaps just a mean fart that didn’t get vented. (eye roll)


#3

I go with the dead mouse in vent theory. This is common enough. The remedy requires disassembling the vent system – a time-consuming task.


#4

Step 1 in the diagnosis. Determine if the smell is stronger with the HVAC on or the HVAC off.
