No cold air from the rear vents

The front dash board vents are ice cold with the a/c on but the rear vents are blowing regular temp air, I can't get the rear vents to blow air conditioned air. Has anyone expirienced this?

I'm curious what the solution is. I have the same issue. Some valve or something from a previous thread I read, but I don't know where it is or how to check it.

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.
