I was told my rear evaporator needs replacing on my '06 T&C as well, an $1,100 fix, and the parts are on huge back order, so a long wait. It is out of warranty.

I took it to a trusted mechanic, and he said there's another option -- disconnect the rear air and recharge the system, just use the front a/c. That was done, and so now the front air works fine. It just takes a little longer to cool the back. The fix was only $375.

The van is out of warranty, and I didn't want to pay $1,100 for a rear evaporator for fear it might happen again because I've heard it's due to vibration and possibly a design defect.

No recall by Chrysler so far. They should take responsibility for this. One dealer I called said there are 4,000 requests per week for rear evaporators, so it's a common problem.

Rear air was not standard in minivans in the past, so it's not so awful to be without it.
