Where Is the condensation drain in a 2002 suburban?

In a 2002 Chevrolet Suburban, the condensation drain is typically located near the evaporator core, which is found inside the dashboard. The drain allows moisture from the air conditioning system to exit the vehicle. You can usually find the drain tube underneath the vehicle, near the firewall on the passenger side. If the drain is clogged, it may cause water to leak inside the cabin.
