Why does the front ac in your 1990 suburban blow cold but the back blows hot?

It is possible that the rear A/C lines have been cut and sealed so the freon stays in the front but does not go to the rear A/C. That is the case on my SububanAnswerThe suburban may have a heater core in the rear blower that is not shutting off. AC cannot blow hot, there is a coil for the AC and a separate coil for the heater. A simple fix is to have a shut off valve fitted under the hood to turn off the hot line to the front and rear blowers.
