No air conditioning in rear compartment. on 1997 Chevrolet G Series Van (G10)

Air conditioning does not blow cold air in the rear of the van. What can I check to see where the problem is. Evaporator in the rear if it has one, refrigerent leak?

possibly. you need to have a shop insert a dye in the system and check for leaks. then they can give you a bid.
as far as doing this at home, i do not reccomend any ac work at home unless you have the equipment and are certified.
