No cold air from the rear vents

If I understand what all of you are saying, the rear fan is operating, but the air is not being cooled in the rear although the front air is being cooled properly. If that is the case, the problem is the Thermostatic Expansion Valve (TXV) located on the rear unit and accessible through the jack access door. The unit will have to be completely evacuated, the TXV will have to be replaced, a vacuum will have to be drawn on the system and then the system will have to be charged with the proper amount of R134a by weight.
