Pollen Filter Housing Bulkhead Water Ingress
ModerateBodywork & RustThe cabin pollen filter on the Ford Fusion is located within the heater bulkhead beneath the windscreen scuttle panel. Over time, the factory foam weather-seal on the pollen filter housing cover deteriorates, dries out, and degrades from exposure to heat and moisture. Rainwater running off the windscreen bypasses the degraded seal and flows directly into the passenger footwell, soaking sound-deadening insulation and risking corrosion to the interior wiring harness and fusebox.
Musty, damp smell inside the cabin accompanied by persistent windscreen fogging in winter, Passenger footwell carpet feels soggy or pools with water after heavy rainfall or washing, Unexplained condensation on interior glass and random warning lights from damp fusebox connections
- Lift the front passenger floor mat and press fingers firmly into the carpet to feel for hidden dampness
- Inspect the plastic scuttle tray at the base of the windscreen for warped plastic or dislodged seals
