2003 T&C AC?

My aunt stopped by with her Town and Country to ask why it was dripping
by the right rear wheel. It was condensation from a cold metal tube
(about 20mm) alongside a warm metal tube (about 10 mm). At the back a
fitting joined them.

It seemed like air conditioning but I didn't understand why evaporation
should be taking place outside the vehicle. Farther forward, two hot 20
mm tubes ran alongside with these two.

I've searched the web but haven't found a description of AC on a
Chrysler van. What are these tubes?

Is the van equipped with rear A/C?? If so, then the tubes could be
refridgerant tubes running to the rear condenser. Not that I am an
expert or anything.

I read online that these vans have two or three zones of AC. I suppose
those tubes have something to do with it. Without knowing how the AC
works, I don't know what those tubes are.

The refrigerant liquid and suction lines to/from the rear air
conditioning. The big one is condensing because it is colder than the
dew point of the air around it.

Ah! I guess the evaporation was occurring inside the vehicle, and the
"connector" I saw under the vehicle was part of that unit.

What about the two 20 mm tubes that ran alongside these tubes forward of
the wheel well? When I touched them I immediately pulled my fingers
away because they seemed burning hot.

If there's also a heater back there, maybe those tubes held coolant.

there is a drain for the rear ac evap. coil there and clear water type fluid
is normal when the ac is on
