We own a 2001 T&C LXi with rear automatic temperature control. Heat
does not come out of any of the in the ceiling nor in the floor. I'm
guessing that the problem lies somewhere between the tubes up front and
the door (?) that controls how much hot & cold air enter into the
vents. I'd like some suggestions for ways to diagnose the problem. I
don't have much experience replacing heater cores, re-charging
refridgerant, etc., but am always eager to try anything at least once.
Thanks.

mean? Does the air not come out or just no heat? the other thing is when
this vehicle is in the rear heat mode you will not get it out of the ceiling
but only out of the floor. If it is just a lack of heat have you checked
your coolant level?

Heat does not come out of any of the rear vents - - only cold air.

Right - when the rear is set to the floor, it continues to blow cold
air when set at the highest temperature.

I have heat in the front. This is what led me to think that the
problem is somewhere between the front tubes and whatever controls the
flow of cool air vs. heat. Good questions. Any thoughts how best to
diagnose a failure in the rear components?

a good start is making sure the rear heat switch is turned on then a look at the
coolant level is the nextr to make sure there is enought and no apparent leakage

Thanks for all the advice. Turns out the coolant level was low and the
rear switch was not set to the floor.
