Air-Conditioning Musty Odor

low
In progress

Safe to keep driving. Fix it when convenient.

If ignored: Left alone, the smell comes back every time the air is switched on and cooling stays weaker than it should be.

Symptoms

  • Musty smell from vents when the AC is on
  • Reduced cooling efficiency

Cause

A clogged cabin air filter and mould growth on the evaporator core.

Solution

Replace the cabin air filter and disinfect the evaporator with an AC cleaner.

Air-Conditioning Musty Odor is a known consideration for the Honda City. Early diagnosis keeps repair costs low.
