Why is there water on my passenger floor when the AC is on?

Water dripping on the passenger floor of your German auto when the A/C is running often means the A/C drain hose is clogged, causing condensation to back up and leak into the cabin instead of safely draining under the vehicle.

• Customer reported symptoms: “water on floor,” “A/C leaking inside,” “wet carpet,” “A/C drips on my foot.”
• Local causes: Pollen, leaves, and debris from Ann Arbor’s tree‑lined streets can clog the A/C drain tube more quickly, especially if the car is parked on the street.
• Why it’s urgent: Prolonged moisture can cause moldy smells, corrosion, and electrical problems in the HVAC housing.
• Typical fix: Clearing the A/C drain line, checking for vehicle interior water damage, and confirming proper condensate flow under the vehicle.

Stadium Auto Service can clear your A/C drain, dry out the A/C housing and ducts, and stop annoying A/C-related water leaks before they lead to larger HVAC or interior problems.
