Where is the condensation drain? - 2005 Lincoln Town Car

No such thing as a condenser drain hose. The condenser sits in front of the radiator.

There should be a drain that allows the condensation to drain outside of the vehicle. Either the drain is clogged and causing the water to back up inside the plenum or your plenum has a crack in it and allowing the condensation to leak out the crack before it can be carried out of the drain. I suppose the drain line could be disconnected from the plenum also.

ac condensation? the best way to un plug the drain get a water hose and put water back up through the drain it should flow out then

And where exactly is this rain coming from? The sun roof? The door seals? Seeping in down in the footwells (soggy carpet)?

Sometimes "rain" can be mistaken for A/C condensate that is not draining due to a plugged condensate drain. If your A/C is running and it's hot and humid out then you should see some water drips on the ground underneath the front area of the vehicle. Let it sit in one location for a few minutes after you come in from driving it. Let it sit for a few minutes with the engine and A/C running. Move the vehicle and look for the telltale wet spots from the condensate drain. If you don't see a wet spot then chances are the drain is plugged. The condensate will back up and drain inside the car ...typically in the passenger footwell and making the carpet wet.

a clogged ac drain will prevent the system from performing properly.
With a clogged drain \,ice tends to build causing the system to have ineffective cooling.The drain hose is located on the firewall,passenger side of vehicle

a/c drain holes plugged,open drains and your problem will be solved.drain holes under car.

Subject:
Water Leaks Into Passenger Compartment Through HVAC Module Condensate Drain Tube When Parked on Incline/Uphill Position (Install Auxiliary Drain Tube Extension)
Models:
2003-2006 Saturn ION Sedans and Coupes
Supercede:
This bulletin is being revised to include the 2005 and 2006 model years. Please discard Corporate Bulletin Number 03-01-39-011A (Section 01 - HVAC).
Condition
When vehicle is parked on an incline with the front end up during a rainstorm or when driving uphill during a rainstorm, water may leak into the passenger compartment through the condensate drain tube opening of the HVAC module.
Cause
Water may drain out of the cowl drain, then drain down the front of the dash panel in the engine compartment and seep into the HVAC module condensate drain tube opening. The water then collects in the heater core cover and upon acceleration may leak into the passenger compartment through the heater core cover seams.
Correction 1. Open the hood and locate the HVAC module condensate drain tube in the engine compartment on the right side of the dash panel.
Important: During installation of the auxiliary drain tube, do not make contact with the HVAC module foam gasket located at the base of the HVAC module condensate drain tube. If the auxiliary drain tube is pushed on too far and makes contact with the foam gasket, water may leak into the passenger compartment.
2. Slide the auxiliary drain tube onto the HVAC module condensate drain tube and make sure that the auxiliary drain tube is angled downwards after installation.

check your drain hose for blockage, if it's clogged up the condensation will leak into the floor

It is not the drain,it is the condensation in the box,the drain is stopped up,use air to blow it out,this will clear the drain.

sounds like it check the a/c fluid drain for any restriction, or leaks
