If you are getting hot air no matter how you adjust the temp control switch, the temp blend door actuator is probably At Fault. The actuator is located under the passenger side of the dash. You will have to remove the lower plastic cover above the passengers foot area to gain access to it.

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.
