Where is the air conditioner drain line on a 2000 Cadillac Eldorado coupe?

The A/C drain line on a 2000 Cadillac Eldorado coupe is located inside the passenger compartment, under the passenger side carpet, near the firewall. It's often difficult to access and requires some disassembly to find and potentially clear a blockage. You'll likely need to remove some trim pieces under the dash.

Important Note: There's no single easily accessible external drain line like some appliances. The condensation drains internally within the vehicle.

Because of the location and difficulty accessing it, it's recommended that you consult a repair manual specific to your 2000 Cadillac Eldorado coupe or take it to a qualified mechanic if you suspect a clogged drain line. Trying to locate it blindly could cause damage to your car's interior.
