Because its location is not readily visible and varies slightly between years, you'll likely need to:
* Consult a repair manual specific to your 2002 Chevy Venture: A Haynes or Chilton manual will show you diagrams and likely pinpoint the drain location.
* Look for the evaporator core: This is the component that produces the condensation. The drain tube will originate near it. It's located inside the vehicle's dashboard area, but you won't be able to see the drain itself from there.
* Search online forums: Search for "2002 Chevy Venture AC drain location" in automotive forums. Owners may have posted pictures or descriptions of the drain location on their vehicles.
Important Note: If your AC is leaking excessively, it's not simply a clogged drain. This points to a more serious issue that needs professional attention, as it could be a refrigerant leak or another problem within the AC system. Don't attempt to fix this yourself unless you have AC repair experience.
