Heat works good both front and rear. All Blowers work. When You turn on the rear A/C it continues to blow warm air.
I have a problem with rear A/C. Front works O.K. but rear only blows warm air. on 2006 Chrysler Town & Country
I have the same problem only the rear is cold and the front is warm. most likely your rear expansion valve is plugged and the compressor is pushing all the freon to the front.
