Where is the air conditioner evaporator drain hose located on a 97 cadillac deville?

The evaporator drain hose on a 1997 Cadillac DeVille is located inside the passenger compartment, behind the glove box. To access it, you'll likely need to remove or at least partially remove the glove box. It's a small-diameter hose that drains condensation from the air conditioning evaporator core. Be prepared to get a little wet as there might be some standing water in the drain line.
