Suburban cabin filter saga: From weird AC smell to cutting open a “sealed” filter slot
My Suburban’s AC developed a sharp odor that honestly smelled like pee — and with young kids at the time, I even wondered if someone had an accident in the car. After sprays failed, deeper research revealed the real cause: GM had sealed the cabin‑filter slot from the factory. Cutting it open and installing a proper filter finally eliminated the smell.
