secondary evaporator not cooling?

Postby liron_al » Thu Mar 09, 2017 12:46 pm

i just got a second evaporator installed in my nissan suv.
it is connected in parallel with the original one and installed in the back of the truck.
after testing for leaks and charging the system up, i get good cooling from the original unit but nothing from the new one..
high pressure side of the new unit feels warm but i get ambient temperature on the low pressure side..
my colleague thinks it's the expansion valve, but i find it hard to believe as the unit is brand new..

any thoughts?
