The drain for the air conditioner on a 2001 Dodge Caravan is located
underneath the vehicle, near the passenger side firewall. It's often a small hose or tube that drains condensation from the AC evaporator. You'll likely need to get under the van to find it. It's not always easily accessible and might be tucked away near other components.
Important Note: It's not always straightforward to locate. A repair manual specific to your 2001 Dodge Caravan model would be the most reliable resource for precise location. Searching online for a diagram specific to your year and model can also be helpful.
