Condensation Drain Tube

Condensation that accumulates in the HVAC housing is drained out of the housing through a tube and on to the ground. The condensation drain tube must be kept open to prevent condensate water from collecting in the bottom of the HVAC housing.

The tapered end of the drain tube is designed to keep contaminants from entering the HVAC housing. If the tube is pinched or blocked, condensate cannot drain, causing water to back up and spill into the passenger compartment. It is normal to see condensate drainage below the vehicle in warm weather. If the tube is damaged, it should be replaced.
