WHERE IS THE REAR AC EVAPORATOR ON 2006 T&C

The AC system front and rear work off the one compressor so yes front and rear use the same Freon.
The front and rear have separate evaporator coils and expansion valves however.

This is a common problem with that year. It is the connection at the rear evaporator. The problem is, the connectors are exposed behind the rear passenger side where salt gets in and eats away at it. Some say it's a bad design. You will need to replace the whole evaporator with the connectors. It is expensive, around $400-$600with labor. Some mechanics are able to disconnect the rear completely for half the price but you will have to relie on the front A/C to cool the whole car.

you are best to take it to a shop that does a/c work to have them evacuate and vacume the system to remove all the air out of the system then recharge it.as moisture will cause problems in the system.also the R134 freon that the system uses is far more dangerous to humans than R12 and can cause serious health problems with little inhalation of the gas.

the most common cause is a defective rear AC expansion valve.

MORE THAN LIKELY THAT REAR A/C EVAPORATOR IS LEAKING..FAIRLY COMMON..HAVE REPLACED MANY OF THESE ON THESE VEHICLES..

water is supposed to drip out of all air conditioners

I'd bet money it's your Rear Evaporator, located behind the back right tire. Mine just went out, which cost $200 to discover, followed by $811 to replace. My co-worker has the same vehicle, and had the same exact problem six months prior. If you google search for "06 grand caravan evaporator" you'll find similar posts. And it's not a recalled item, as of this writing.

It does have air conditioning installed. It may also have rear a/c. The rear a/c evaporator is probably leaking freon. I have replaced many rear evaporators on 2006 and 2007 Chrysler minivans as a result of a design change in 2006. Recharge the a/c and add dye to the system. If it has rear air, look behind the right rear wheel in the fender area under the car where the a/c lines go into the body.

Chrysler has recently extended the warranty for this problem to 7 years/70,000 miles. They will also pay for repairs you have already had on this rear evaporator. Contact your dealer or call 800-992-1997.
