Where is the evaporator box drain hose on a 1999 Dodge Ram 2500?

The evaporator drain hose location on a 1999 Dodge Ram 2500 isn't easily accessible and its precise location varies slightly depending on the specific trim and body style (regular cab, extended cab, crew cab). It's generally located behind the glovebox, within the dashboard, and leads down through the firewall to drain condensation from the air conditioning system.

Because it's hidden inside the dash, you'll likely need to remove or partially remove the glovebox to even see it. This often involves removing screws and possibly some clips.

Caution: Working in this area requires some mechanical aptitude and patience. If you're not comfortable with this type of work, it's best to consult a mechanic or auto repair shop. Incorrectly working on the dashboard can lead to further damage. Consult a repair manual specific to your 1999 Dodge Ram 2500 for detailed instructions.
