99 ac issue

[Nortex]

My front ac is ice cold but my rear in Luke warm. I had the freon checked and its good. Would it be a blend door issue?

thermo-expansion valve on the rear evaporator is another likely cause.

I got the same problem. Sunlit do you have any suggestions on how to check those 2 things?

you can open the hvac box and watch for proper movement of the door. for the valve having multiple thermometers that can sense the evap tubes in and out will help identify a valve issues.
